We did a quick back of the envelope calculations. Unless we were getting free electricity, it isn't even worth it to use S9s to mine anymore.
Even if you had free power, it probably isn't worth it to install Antminer S9's because the buildout will be expensive. Even if you could get the miners for $120 each, the cooling + electric circuits will easily cost $200+ for each one (depends on labor cost). So each S9 actually costs $320. The Bitmain T15 or S15 would be better.


After some consideration we decided to announce availability of miner hosting at our facility again.

Sunbreak Electronics LLC is a datacenter located in Oregon

We started hosting mining equipment back in late 2014 as JeffColo, in 2017 we started Sunbreak Electronics LLC and built a new facility.

You can see our previous announcement here - https://bitcointalk.org/index.php?topic=1467198.0

Our facility was designed to be a mixed use wholesale colocation datacenter for businesses and individuals who are sensitive to power costs and equipment sales tax.

Electrical expenses are paid directly to the utility and you only pay the datacenter for the space and connectivity you are leasing.

We have 48 openings for wholesale colocation right now.

Each colocation package is available for $1600/month and includes

- Metered Utility Service - 200A 3P 208 VAC ( Paid direct to utility @ ~$0.05/kWh )
- ASHRAE Class A1 Environmental Control ( 59F - 89F, 73F Typical, 20% - 80% RH, MERV 11 Filtration )
- 2 x 42U APC 3150N 19" Racks

Adjacent pairs of racks are available on a diverse power path. This allows for combined or redundant power delivery to 4 racks.

This colocation utilizes pressurized hot aisles. Diligent use of blanking panels and careful attention to fan selection is necessary to operate correctly.

Can be used for crypto currency mining, hyperscalers, AI, big data or something else of similar power density.

Full selection of communications services available

- Dark fiber (Astound, CBX, WIN)

Resurrecting this thread..

Very interesting discourse.. I am a miner & colo myself and I totally agree with the "ROI" required. If its too much hassle, we'd rather drop customers. Its easier to deal with 1 customer with 1000 miners than 1000 customers with 1 miner each.

I have to agree. Back in 2017 we started construction on a general purpose datacenter in Oregon rather than a mining specific one. Between 2017-2020, crypto miners were the bulk of our revenue, but it was also the hardest earned and the most inconsistent.

The boom/bust cycle of crypto is difficult for any datacenter to accommodate. Just for historical context, in November 2018 the market dropped below profitability for our customers. Overnight everyone was asking us to turn their machines off, so we did. Unfortunately that also meant nearly 100% of our revenue stopped.

At the time, my colleague argued that if none of our customers were paying, we should evict them, have them collect their equipment and reclaim the space. However it would have been counter productive, there was absolutely zero demand to host new mining equipment. Which was pretty evident as some of our customers tried to sell their equipment with little success.

After 6 months, in May 2019 the price did turn around and all of our customers took control of their machines again. Unfortunately this only lasted 5 months until November 2019 when increasing difficulty forced all of our customers to shut off again. In June 2020 the halving occurred, which pretty much assured that equipment was never getting powered on again.

Over the course of operating 24 months, we only generated a profit for a combined 10 months. The other 14 months with non-paying "idle" customers consumed whatever profit we had managed to make previously and took us negative into the red.

Today we have almost no crypto customers, although we do have a growing number of "traditional" datacenter customers. If we hadn't built the facility with customer diversity in mind we would have perished like everyone else.

Which brings me to my point, the "mining facility" concept has little chance to succeed even with scales 10 MW and beyond. Even when you have low priced power, there are unavoidable overheads. Rent or mortgage payments, construction loans, staffing costs, local taxes, licensing, insurance, accounting fees, property tax, etc.

Obviously there are some economies of scale that can help average these costs out, but we have found that beyond a certain scale the cost actually goes up. There are a lot of cost saving opportunities when you don't have to buy everything new, pay premiums for expediting construction, permits, lawyers, etc.

No matter how you balance it, you always end up paying ~$0.04/kWh in overhead.

- Want to mine at home? Then your stuck paying for retail power with a 50% premium over commercial
- Found a mining facility with super cheap hosting in some remote country? Now your exposed to a very likely risk of losing your equipment.
- Found a warehouse to rent for $2k/month with 400 amps of power? That's $4k/month in power that your paying a 50% premium on thru rent.
- Decided to go big! Get a loan for $3M to build a 10 MW facility. Paying your loan is equivalent to paying a 50% premium on power for 24-36 months.

Ironically, I have been considering hosting mining customers again now that they aren't critical to the success of our business. I just need to find a creative way to more appropriately split the risk between hosting provider and miner.

6  Economy / Service Announcements / Re: Cloudsmash.io - Decentralized VPS Cloud Open To The Public on: February 24, 2018, 02:10:24 AM
Glad to hear that this project is still going! I thought for a bit that it was vaporware since I had not heard of any updates about it since your previous post.  Do you have any sort of general timeline for the project so as to know when we can expect it to open to the public or have an open-beta, sort of?

The summer was a pretty hectic one. In addition to developing Cloudsmash, I also run a small datacenter called JeffColo.

In 2017, we decided to reorg and expand our datacenter into a larger space. We have had significant delays getting the new facility online. Before the move I suspected there would be problems, so in July I moved all the Oregon Cloudsmash gear down to Hurricane Electric in Fremont, CA.

The migration to Fremont was an excellent test for the resiliency of the mesh. Multiple peering points were dropped, vm's were migrated to alternate sites, hardware was packed up and driven to it's new home. Once back online, we established our new peering and began to migrate vm's back. It all worked perfectly, with zero customer downtime.

The move also allowed us to test using a virtualized equipment stack. This means that we have no physcial routers, firewalls, etc. Our servers connect to simple switches and rely on virtualized routers to establish upstream peering with HE.net. We received a 10 Gbps network drop, so we now get to validate networking performance beyond the gigabit threshold. Recently we have been able to get our virtual router instances to forward at the full 10 Gbps rate despite running on Westmere hardware from 2010.

The previous beta round quota had been filled and I've been accepting feedback for the last several months. There have been small improvements here and there, mainly surrounding network performance and reliability.

Recently we began the process for hiring an architecture engineer. The selection process has been going well and it looks like we may have our first Cloudsmash developer coming onboard soon. I expect to have another consumer beta round in late Spring 2018 and hopefully will do a very limited alpha round for providers in mid-Summer 2018.

Quote from: btcton
I have honestly never thought or seen anything like this before making decentralized VPSs and would love to see how such a technology could fare in a near-production environment. I do not have any specific host services in mind, but I do wish to see what can be accomplished with it.

I had not either and was frustrated that it didn't exist. It's certainly not vaporware, at this time it's a well tested stable platform that desperately needs a good web interface to interact with consumers and providers. Cloudsmash now has 14 pop's and several hypervisor locations, the network has experienced zero downtime since I brought it up in August 2016. It's kind of a living, breathing thing.
7  Economy / Service Announcements / Re: [ANN] JeffColo - 3.5 MW / Miner Hosting / Colocation - West Coast (DC) on: January 03, 2018, 06:35:56 AM
I’m “patiently” awaiting an update as well.   Grin

Any update on availability here with Jeffcolo?

I know people have been patiently waiting for an update and I haven't given one in awhile. We have been expediting all of our engineering and plan reviews with a feverish pace. Unfortunately at the same time we also got an early present as Bitmain shipped a significant quantity of miners almost a month earlier than expected. Combined with the holiday season, the last 40 days have been a whirlwind.

Here is the update for everyone following this announcement.

We have 1 MW online at the moment that has validated our adapted modular design for indoor operation. Our electrical engineer has reworked the power distribution design in order to distribute the (48) 200 amp services throughout the building. Additionally we had to hire a civil engineer to work out all the new vault requirements for these new larger than life 1500 kVA transformers. All of this got submitted to local code enforcement for plan review, it passed and we received our permit to start work. Getting this all pulled together going into the holidays was no small feat. All of this information was submitted to the local utility and we are waiting for them to come back with a cost and scheduled installation date for the first transformer.

These modifications shouldn't have been that big of a deal. However we had a benefit with the outdoor version of our module. When considering code enforcement, the outdoor module was considered its own independent structure. Unfortunately when you bring all that power in under one roof there are huge changes that have to be made. I could get started on all the nuances, but it probably deserves it's own book.

Meanwhile we have contracted with a local excavation company that should be starting on the groundwork for the transformer pads and underground conduit maze. All that conduit is going to be quite the spectacle when it's all done and ready to back fill. The excavation company will have the horizontal boring work done to bring the 12 kV primary power to our new vaults.

At the same time we are having our boring work done for the electrical, we will also have boring done for our dark fiber feed into the regional internet exchange. Currently we are using symmetrical gigabit fiber from a local provider as our primary means of connectivity.

Our electrical supplier let us know that the switchgear should be delivered soon and our electrician is ready to go. We found a supplier who indicated they could have the 15,000ft of 300 MCM wire to us within 2 weeks.

While the electrical work is being done we will be having the building exterior modified to accommodate the air flow requirements for both incoming and outgoing air. A dedicated firewalled mechanical room will need to be built for power ingress.

tldr;

The good news is that things are progressing, the bad news is that we were way to optimistic about getting things done over the holidays. We are still at the mercy of the power utilities schedule, so at this time it's impossible to know precisely when things will actually be ready. However I believe all the things I described above should be done in 4-6 weeks from now and hopefully the utility will have us on their schedule for our first transformer install shortly after.

Also, we recently hired help for coordinating with customers. More importantly now than ever please use the 'hosting@jeffcolo.net' email address and you should get a far faster reply than you would from me.

As you can imagine, we are working hard every day to make this thing a reality.

We only have a point of presence in Manchester to relay our traffic into our network, hypervisors could be located anywhere.

However that does bring up an interesting point, I'll see if I can start maintaining a list of hypervisor locations.

Currently they are;

  • Fremont, California USA
  • Portland, Oregon USA
  • Berkeley Springs, West Virginia USA
  • Ashburn, Virginia USA
  • Amsterdam, NL

Is there any ETA (I assume a very rough one considering you guys are still in the beta testing phase) for when you plan to open the project for public consumption? What other cloud providers do you expect to be competing against? Is it the DigitalOcean / AWS Lightsail sort that simply provide cloud services or bigger infrastructure-as-a-service giants such as Google Cloud Platform and Microsoft Azure? I am talking functionality-wise rather than scale-wise, at least to begin with.

On a side note, your website seems to be down still. Is there any official way to follow the progress of this project? Are there any plans on creating a fully fledged website with the information or is it still too early for that?

I'm hoping that we will open to the general public for VPS use sometime in the fall of 2017. It might not be until early in 2018 that we open to the general public for server contributors.

There are some "IaaS" aspects to it in terms of the seamless global networking, automated storage replication and fault tolerance. However it is mainly targeted at unmanaged services. I would expect that people would build managed services on top of it.



That sounds great. The website still seems to be down, however.  Are there any official channels to obtain constant updates on this project? If not, what way could I be kept up to date on what is happening and the potential release dates as well as open services? I definitely do not consider myself knowledgeable enough to know how much work this takes or even the back-end or structure of this shared cloud, which is the main reason why I would like to know potential ETAs and milestones for the project as soon as possible.

Yeah, no website yet. What can I say? I'm a better packet wrangler than graphic designer. If anyone wants to help with a website I am open to suggestions. Currently this project is operated only by myself. I am actively looking to hire someone for help though, anyone interested?

Over the summer I did work on a web app for user interaction and it is mostly working. I just need to tie it into the backend and it should allow people to manage their virtual machines from the comfort of their web browsers. For now I handle all the administration (power on, power off, os install), however once the machine is running I'm basically hands off and the end user has full control of their environment.

If I understand correctly, this project is still in the conceptual design/starting implementation phase still. This means that they are nowhere close to actually delivering a finalized product for the end user/consumer (us). In the last update they said that they have plans for opening the service to the general public in the fall of 2017, but they did warn that it is possible that it will not actually be happening until later next year. Given how I still cannot find a website for them, I believe it is too early to be asking for offers. If there are any updates I am not aware of please let me know.

Actually the core infrastructure all works and has been operating without downtime since August 2016. It's quite beyond the conceptual stage, the real question is scale, how many people and machines can I load up on my network topology before things start getting problematic.

The reason for the beta rounds is to slowly introduce additional people onto the platform to monitor and observe the network and any problems the beta applicant might run into.

There will be several beta rounds for virtual machine consumers and separate beta rounds for virtual machine providers. We are currently in our second round of beta applicants for consumers. If you are interested in getting a virtual machine please let me know by email at decentralizedvpscloud@gmail.com

Well good news, it has taken forever but the Hong Kong peering point is online. The only downside is that currently we are only receiving traffic through the pop and are unable to originate traffic from there. I'm sure it will get worked out eventually. The HK peering point is connected directly to the HKIX (Hong Kong Internet Exchange).

Additionally I expect that the Chicago and Buffalo pop's will be coming online sometime this week.

Singapore is still a work in progress.

Good news, the Chicago and Buffalo pop's are online and working. Thanks to Nexeon for providing the hosting for those.

In other news, the Hong Kong and Singapore providers are just awful. I've decided to shutdown those pop's for now, they have created far more problems than they have solved.
12  Economy / Service Announcements / Re: [ANN] JeffColo - 3.5 MW / Miner Hosting / Colocation - West Coast (DC) on: October 18, 2017, 11:19:40 AM
I wanted to update everyone following this announcement on the state of things at the moment.

First and foremost, we did take possession of our new datacenter space on 09/11/2017. We were able to quickly get the first 500 kW service up and running that first week and were busy moving customer gear into it. Starting in October we were able to add an additional service for the second 500 kW service. This was supposed to be the cadence we would continue following until the new year when we planned to have our entire 3 MW available for colocation customers.

Unfortunately there have been delays thrown into the plan by both the local utility and also with our electrical equipment suppliers. The problem with the utility stemmed around our stated load calculations and the utilities lack of belief in them. The utility here has never had to size equipment for a datacenter before and they undersized our service delivery transformers despite our indicated load figures. We were unaware of the sizing problem since the transformers have no significant information located on the exterior.

The first 500 kW service turned out to be running on a 300 kVA transformer which is being upgraded this Friday to a more suitable 500 kVA unit since it was determined that we are severely overloading it to the point of leaking oil.

The second 500 kW service in turn was also on a similar undersized transformer that doesn't seem to match their records. At this point we are unsure what size it actually is and have been instructed to halt adding any additional load until the size can be validated. We have been monitoring the temperature rise of that transformer and found it to be operating well within tolerances. Unfortunately the utility did not agree with our assessment and we will need to wait until Friday to find out what the situation is.

At this point the utility determined the existing plan for power distribution was no longer going to work as our "constant" load was not within their expectations. They wanted to revisit the plan to oversize our transformers and also potentially shorten our timeline to getting a significant amount of capacity online. They proposed that instead of using 6 x 500 kVA transformers as originally planned that instead they would site 3 x 1500 kVA transformers over the next 3 months and limit our usage to no more than 3.5 MW ensuring that we are only ever running the transformers at a maximum of 73% utilization.

That means that as soon as that first 1500 kVA transformer is placed, we would be bringing on an additional 1.15 MW immediately. That could certainly accelerate customer placement. Unfortunately this also means it all has to go back to the electrical and civil engineers to update the design, back to the county for a plan review of the changes and then finally onto the build out schedule at the utility. I have no idea how long this will take, we are trying to expedite it as much as possible.

Unfortunately shifting from 500 kVA to 1500 kVA transformers significantly increases the fault current requirements of down stream equipment. This resulted in some design changes to the type of disconnects and respective fuses. Fortunately it didn't change any of the customer facing switch gear (meters).

The unfortunate part is the update from our electrical supplier on the state of our order for that customer facing switchgear. Apparently due to the events in Texas, Florida and Puerto Rico, electrical equipment has become very high demand and disaster relief areas get first priority. We were given an estimate of approximately 6-8 weeks before we see any of that gear. I really hope it ends up being sooner, but I wouldn't bet on it.

I suspect that the utility changes and respective local government involvement will likely cause a similar delay. We're going to try to make enough progress with the utility so that by the time work begins it will be coordinated fairly closely with the arrival of our long awaited switchgear.

All this means that if you were given an availability date of late October to early November you can expect it now to be closer to late December to early January.

Can you post some photos / videos of your datacenter?

Waiting for your reply to my above questions.

I believe you were sent a PM, let me know if you still have questions.

E-mail sent last week. No respond yet. Still waiting.

As stated above, we are busy building out at this time. We will not be responding to hosting requests quickly.

With the current state of the waiting list we have no available capacity opening up until late December 2017 to early January 2018.

If you sent us an email asking for a capacity reservation then you will be added to the list in the chronological order we receive the emails. We do not update the list on this announcement page everyday, we will attempt to update it every couple of weeks.

Obviously customer equipment that is showing up now needs to be setup and running as quickly as possible so our buildout is of the most importance in priorities.

Hosting requests for capacity that isn't built out yet must take a lower priority. I know this might seem hard to understand, but if you are a customer who has had equipment showing up in the last two weeks then you probably value this order of priorities quite a bit.

The next 30-40 days is crunch time and we will be extra busy receiving the last of the equipment and setting up the new datacenter space. Due to this we have started to fall behind in responding to hosting requests.

We understand it is critical to avoid delays in getting your equipment up and running as soon as it ships. Many of the customer requests we receive want absolute dates on power and space availability. If you are uncomfortable sending equipment to us for fear of delay, please host it yourself until the space is move in ready. Then ship it to us at that time to avoid any possible delays.

Prospective customers who have corresponded with us know that there is a capacity reservation waiting list for the various stages of our expansion. In an effort to stream line our hosting request process we decided to post our waiting list on the top of this service announcement page.

The reservations on the waiting list will be be fulfilled in first in first out order. User identities in the list will be replaced with random values known only by us and by the requester. Until the list is full you are assured that you have the option to host with us when it becomes available. If you request capacity after the list is full then you would only get an opportunity to host your equipment with us if someone else decides to refuse the offer.

Send us requests for hosting at hosting@jeffcolo.net with the quantity, brand and model of the machines along with the total power consumption you expect to use. The list will be updated with your request in chronological order. If for some reason we are taking awhile to reply, rest assured that as long as you sent us a request the timestamp on the email will ensure your position.

When power and space become available we will go through the waiting list, when your name comes up you will be given the opportunity to commit to the agreement or refuse it at that time. If you refuse, the power allocation you had requested will passed forward to the next person on the list.

We have a master service agreement that we can provide for your review. Due to the waiting list there is no reason to sign the agreement immediately. We can go through that when the power actually becomes available and the space is move in ready.

Others have stated they are willing to accept the risk of delays and would like to send us their equipment directly from the manufacturer in order to save shipping expenses and take advantage of Oregon's lack of sales tax. Just realize that as hard as we may try, delays are possible and often outside our control. We will do our best to minimize delays as much as possible.

Thanks
