FYI, I finally did reach sushi via e-mail.  He said that the Colorado hosting facility that he had sub'd to was bad.  Not sure exactly what that means, but he was able to move my units to a new facility and got them up and running.  He also gave me a few days of excess hash power though not enough to compensate for almost 1 month that I was down on most units.  In fairness, when i reach sushi (josh I think) he has been very responsive. 

Reaching him and getting his attention, that is the trick.  I suggest to anyone with similar problems that you send an email to sushi (do not use the web trouble ticket system) and include your order number(s) and a detailed history of your problems, as well as a short and concise statement in the first paragraph of what you want him to do.  be polite but firm.  Send the email every day until you get a response, and post the email here as I did so everyone can see what problems remain.  Sushi had said that Skype was the best option for him, but I have never been able to reach him on Skype.  YMMV.  When he fixes your issue, post here to so at least folks know he is not a scammer (having serious business issues and lacking sufficient resources is not the same as scamming, and I withdraw that accusation now that he has responded). 

OMG, I just got an email from sushi's website saying that a group buy for the S2 will be starting.  DO NOT PARTICIPATE!  He can't handle what he's already done; he's neglecting previous group buys.  Don't buy any more.  Just go to bitmaintech.com directly.

For what it's worth, my S1 has been running again for the last 36 hours, just checked back on the pool and to my amazement it's got hashes coming in again. Hope to see it finish the 2 more months of prepaid hosting.

Sushi is trying hard to correct what happened FYI.  He seems very overworked.  I am piecing together (e.g., this is a wild assed educated guess) that he turned his hosting business over to some third party, and that company/person went AWOL or worse.  I am not happy with this situation, and I wish that Sushi would have come to us and told us what was happening rather than trying to deal with the issue behind the scenes.  However, he seems to be back and trying to fix things and he seems honorable (as was my first impression before all the issues hit).  So my suggestion would be to put together a **new** e-mail that sets forth your problems, your order number(s), and your request **succinctly**.  (he doesn't seem to get PMs, so I am wild-ass guessing that maybe he turned over that account to the same scumbag company, or maybe sushi just can't handle the volume, IDK but e-mails are the only way I have reached him so far). 

While everyone can approach the situation in their own way, I would suggest remaining polite and trying to work with Sushi.  He is not IMHO a bad guy, but maybe did not make the best communications decisions when confronted with a problem.  In any case, given that a lot of folks have issues, please consider keeping your e-mail concise, but also include everything he needs to find your miners and fix the problem (order #, order date, hosting site if known by you,  your contact info, and problems you are having (e.g., miner down, miner not hashing at full speed, etc.)).  Sending an email like I was doing for a while that just says "&(*&(#@(*&@!!! wtf why haven't you answered my e-mails/PMs" is probably not going to work because then Sushi has to find your past e-mails and PMs.  So keep it concise but inclusive enough to be self-contained, and try to avoid letting off steam.

I do think that there should be some comp from sushi but if your miners are down the first priority is to get them back to hashing so keep the e-mail to that is my advice.

I'll chime in and say that I've got two miners hosted with Sushi and after some down time and some emails they are back up and running fine.  He is slow to respond to emails, but I can say that he's addressed my issues without any problems.

ftfy - nice rant btw

Knock on wood but my Ant has been hashing away very stable for the last 6 days.

Therefor I suggest doing the same as eightcylinders, send Josh a decent (and very clear) email with what your problem is. Hopefully you'll get back in the game soon too!

One of the ants that sushi was supposed to send me stopped mining yesterday. Anyone else lose hashing?

With all the complaints here about getting ripped off by Sushi, why would anyone even consider purchsing from this guy?
Too many issues, many people believe he has scammed them and they are Never going to see their BC or ants again...
Greaterninja  at  Ninjatech.org  is an reputable place to purchase Antminers.   Great customer service.   Support an honest business.

Ever since Sushi got my miners back online a few weeks ago I've had no problems.
