Ethermine ETH Pool (biggest ETH pool) down last 4h

[cjclm7]

It seems the biggest ETH Pool (https://ethermine.org/) is down for the last 4hrs. Does anyone confirms it is working again? What about all miners work of last 4hrs?

Some links (to check last 4h no updates):

cannot reach helpdesk either

Lots of pools and servers have been down today due to power problem on a EU server.
Try switching your pool proxy from eu1. to us1. for the time being. That should sort it.

My rigs are all sorted now on the EU servers. Ethermine, Nanopool and Minerpool. Maybe double check yours.

OVH went down this morning from 1 hour the servers are back online but still there is some time out

Yes, it seems it in online and mining again. It was down for about 5 hours.

Question now is: what about the 5 hours the miners were actively mining (those who did not switch/move to other pool) for this Pool? For who were they mining? Did they completely lost 5 hours production time?
