all devices failed over to a non kano pool just now....
pool 0 and pool 1 are stratum and nya, both were not accessible for a very short time.
seen this on awesome miner where all devices failed over to my pool 2
Stratum (which is now in Oregon) had a failover for everyone on stratum at 7:19am UTC
However NYA (different provider than Stratum) locked up temporarily a few minutes later though it didn't disconnect, so either failover failed as often happens or it failed to connect to NYA a few minutes later due to the temporary lockup and thus ended up on the pool3
All the Stratum nodes (AWSLS) reconnected pretty much immediately so the usual cgminer fail of waiting 5 minutes also keeps it off pool1.
All OK again.
