I just ordered 2 of batch 8 yesterday. I received an email this morning they received my payment. Anyone know whats going on with the website, I'm a little sketched out?

Also on a side note can someone tell me what the monthly power bill for one of these S7s is?

It could have been a DOS attack.  I know several pools and websites have had DOS attacks the last several days.

Just found a Hosting Company to take a few S7s and run them for me.  Has anyone heard of or conducted business with:  ASICSPACE in Wenatchee, WA 98801 USA?  http://www.asicspace.com/

Let me know if you know anything.  Thanks!

I'd go with one of the Canadian companies for the best rates. Anyway, here's a list of hosting companies:

Thanks for all of the inputs that you have given me!  This forum has to be one of the best forums for information out there. Again, Thanks to all of you that help me in my Bitcoin journey.

I noticed.  I was probably the first one to buy.  I've been refreshing the webpage every 2 to 5 minutes since they were down.  The moment it came on line, I bought 23 of them.  I wish my other BTC was available on CoinBase so I could have bought more.  Oh well...

EDIT:  9 x S7's will have to sit on the sidelines until I get my power upgraded within the next two weeks.  That's if they arrive before my power is upgraded.

Damnit. I ordered a B8 yesterday for 4BTC. I have the worst luck.. Just emailed bitmain asking them to charge me 3.1 I stead and keep the 0.9 in my account to be used on my next order.

Dmwardjr, did the engineer come by and approve the upgrade?

Sucks

It's like when I bought 2 Batch 1 in BTC.

I hope they grant you the new price

Sorry for the delay.  I've been doing a lot of math.

No, he is supposed to be here this coming week since he did not make it by this week.  When he sees what I have already, hears my plans and sees my invoice for what is on the way, I should have no problem getting a total of 600 amps...  Hopefully.  I'm looking at ultimately running approximately 116,700 watts (380 TH/s) of rigs, exhaust fans, etc... out of my house.  I will have 44,700 watts going when those 23 units arrive and I have the power upgraded.  I have to get quotes from different electrical contractors after I speak with the engineer.  I have 4 contractors on the ready just waiting for me to give them the go ahead to come out and have a look for a quote.  

I had one guy who came out and told me, "We charge a 'flat rate' of $5,000 for a 400 amp service."  I said to myself, "Well, this guy can take a hike."  He would want to charge more than this for 600.  Geez.  The guy never bothered to create an itemized list of costs in materials, etc.  I was still nice to him and he ended up allowing me to take a photo of the Senior Engineer's business card he had for my area.  It pays to be kind regardless.  That's how I got the ball rolling with the engineering department.

The power company has already said they would do the feeder cable and transformer at no charge providing I use the amount of power I say I'm going to use for at least 5 to 6 months [Which I am].  Otherwise, they would back charge me for the labor and materials used to upgrade my power.

It looks like I'm probably going to have all of this going before I play in several poker tournaments the end of January.  I've almost got my wife up to par on how to handle the rigs while I'm gone.  She's the greatest!!!

I got my batch 8 yesterday I didn't have any time for testing or disassembly.
I only hooked it online before leaving for trip, some observations: same kind of noise as batch 7 (which don't resonate so much anymore after some use), I didn't see any dc/dc converters inside atleast not S1 size, speed was 4.5-4.6Th/s with only 10min uptime, same room where I started batch 7 and temps were 47-50c inlet fan was 100rpm faster (less chips, coolers and restcriction for airflow?).

Obduction for miner tomorrow😊

Batch 7 is jumping a lot from pool to pool or reporting a lot higher or lower hashspeeds at pool side than at miner, any thoughts of this?

[as4uz]

Great, I bought one yesterday, now I lost 0.874 which is great and I also have to pay higher VAT taxes (because I bought it when it was 1650, now it's 1300) when it arrives, great job Bitmain.

Thanks for the info.  I won't be upgrading.  What's the date on the firmware?

EDIT:  Never mind... I see it's December 11

Anyone have a coupon for s-7's  my bitmaintech name is philipma1957 same as here.

It is a bit frustrating that I was never compensated for a slow 4500gh batch 1 machine   and a slow delivery of my batch 2 machine.

I purchased 5 S-7's from bitmaintech and 1 from lee to be hosted in china

of the 5 direct from bitmaintech  4 hash well 1 hashes poorly 1 was delivered late.

A coupon would be the correct  thing for them to do, but nothing.

If anyone has a coupon for me you can pm.  thanks phil
