They were not failing over. This was the subject of 2 tickets which were simply closed after several days. For a few weeks the proxy seemed to be working, but we had 2 rental where the proxy messed up, the renter got nothing, we still had to pay our end of the fee, and lost all the mining time.
That's pretty bad, if an upstream pool connection fails the proxy should either fail all the connections to a backup or cut all its downstream connections so the miners failover to backups. They also shouldn't rely on upstream hash-rate validation as it could be inaccurate due to extremely high diff or other weird pool issues it should be measured on the downstream miner connection side.

I bought a scrypt cloud miner from mintsy and sadly a Lot of External sites I point at do not function at all.  suprnova, nicehash/westhash etc.  So I went and just pointed at their own servers and so far so good there.  Just wish I could point the miner at different altcoins than mintsy has listed.  Pretty much when I figured out that issue I have just had the miner pointed at Litecoin in hopes that I will come out ahead of what I spent.

Agree completely. There's a lot of potential here for a great service but these are the exact weaknesses that caused us to pull all but 600 Gh/s. It's kind of fun to have a little hash there to mine some alts (MZC has been doing well past couple days) but it's not worth the effort to put our larger rentals up and risk this scenario. My guess is that digitalX doesn't have a big team behind Mintsy but its frustrating that these core issues remain unacknowledged and unaddressed.

We are used to the models/functions of the other sites, where true failover occurs if the renter picks a bad pool, etc.

I'd like to see these issues addressed, as again, there is potential here. Especially for anyone who likes a few alts on the side.

Have you tried the iSpace pools? Just curious. There seems to be a pretty large list of external pools that don't work. It might make sense to restrict or disable this functionality until the proxy is functioning as it should.

I have put a group of testers on some of the pools mentioned. If you have a list of pools beyond what is posted already that you want me to figure out why its not mining list them here and we will see what the issue is. I am currently using multipool.us which is working with my contracts.

To summarize my personal observations with external and Mintsy pools:

1. Antpool SHA-256 does not work.

2. WestHash SHA-256 did not work last time we tried ~ 2 weeks ago

3. F2Pool SHA-256 works properly but double reports hashrate.
--I have seen this with rentals too. I cannot see what pool renter picks but some rentals show well over the speed of the rig.

4. The PPCoin pool looks stuck. Even when I pointed hash to it, it showed no accepted shares or change in the hash of the pool.

5. The other SHA-256 Mintsy pools appear to work well. We use ACoin, MazaCoin, Unbreakable, and Unobtainium regularly.

Out of all of these the only one that doesn't make sense is Antpool as that's overall a pretty standard pool, could be an IP block or something like that but I haven't had issues like this there before.
Westhash/Nicehash will depend a lot on the proxy implementation but it is by far the hardest pool to get a proxy working properly due to obvious reasons.
The F2Pool bug is just a flaw in how the proxy handles share validation, now that I think about it a renter might be able to exploit this type of bug and get free hashpower(depending on proxy implementation details).

It also didn't work for me. I didn't bother contacting support as slush's pool worked and it's no difference to me. Thing is, my hashrate has been REALLY unstable. When mining in an external pool my workers went offline very often even when I had 100% of my hashrate allocated there. So I ended up pointing all my hashrate at mintsy's pool, but it's still really unstable. I was hoping that the payouts would at least be consistent, 100 Gh/s (the rate I paid for) would have been making 0.001 BTC. I understand that the hashrate can be unstable, but if it keeps like that, I'm not even going to come close to what I paid for the plan. Every payout I get each day has been well below what 100 Gh/s could have mined. Some days I don't even get a payout at all.

I like the idea of buying mining contracts that can be pointed to external pools, but so far, I'm not really having a great experience with mintsy.

I'm hoping you can clarify this a bit - you mentioned that payouts some days are less than what 100 Gh/s  should earn... but you are also mining at PPLNS pools... I'm mining with my own hardware so the Mintsy contracts aren't an issue for me, so much as the proxy and it not working with certain pools. Not to mention if you're mining the Altcoin pools whether you'll make the PPS amt of BTC or equivalent is also a gamble, again factoring in that Mintsy pools use a PPLNS model.

I'm using the contract's hash power, not pointed to external pools. I figured that mining to external pools wasn't ideal since my workers there were going offline often. Support agent I got a reply from was trying to be helpful, but I'm not blaming him/her since I guess there's no way for support agents to fix such issues.

I'm still giving mitsy the benefit of the doubt though, hopefully they'll find a way to fix serious issues soon.

Hm we have another problem here:

As of 5/15 UNO is merge mined with BTC. However the Mintsy UNO pool appears to be in operation. Not sure what this means but the UNO network did hit 1.2 Ph/s at one point. I know the Mintsy pool is no longer finding blocks...

I also have not seen a response on the PPC pool being stuck for close to 7 weeks now.

I would like to know how a proxy could give out a nonce2len larger than the upstream pools they connect to.
It would appear whoever made this proxy fucked that up big time.
You are basically going to be mining on garbage because of this and won't failover, this would be why the miners would be mining but the renter was getting no pool side credit and no hashrate was showing up.
Mintsy should probably comp mining rig operators that they took refunds from since the hashrate was being provided but mintsy was not giving the hashrate to the renter due to messed up internal settings.

Well it appears the UNO pool is now offline. No word on whether it's merged with any of the other SHA coins, but I'd like to see Mintsy follow iSpace's lead and merge UNO with all the other SHA coins.

EDIT: We've moved our altcoin mining to MMPool and iSpace until Mintsy can get things sorted out with pools and proxy.

In more than one support ticket I pointed out that Mintsy should be comping people in this scenario and the tickets were simply closed. I'm not sure if there just simply aren't enough resources to attend to maintaining this site but the banners are all over Cryptsy, amongst other places, and it just doesn't work right. Seems like its time to either hire some more devs or shut 'er down.

Also have a 100 Gh/s contract. Mine spikes at 22 Th/s for a second today but overall it's the same. Unstable hashrate and payouts, same from day 1.

Hey guys, I bought some sha256 shares and have been running them for several weeks now.  Would love to report on it and also get some feedback from mintsy themselves.

I purchased 90 day SH256 minings shares.  After a few weeks of mining the ROI is 143 daysThis is a guaranteed loss.  i'm interested if Mintsy will do something extra for us?  If we I can edit my review Smiley

It's been running a while now so even if luck does come into play I don't see how I'll earn my money back.  Hopefully Mintsy will comment or change their service but in the meantime I highly recommend that people do not invest.

Yeah, their cloud hashing isn't worth it as it is now. And from what it seems there's not much their support can do about it too. I was encouraged to contact them after noticing my hashrate is unstable and my workers go offline when mining at external pools. The reply I got from the support wasn't that helpful.

We recently got some new Scrypt HW and tried Mintsy as part of our testing; for anyone using Alcheminers you will get 100% rejects using Mintsy.

How well do the scrypt miners compare on here are they worth it to RIO on it or nowhere near. Was looking into other cloud contract people who have 50% fee and take too long to brake even on equipment.

1 TH costs around $800 with them and would never brake even that's on a 5 year contract for sha.

Is mintsy any better on the scrypt side of things or waste of $ put into it?
