Sep 24 "No counterparty servers are currently available"

I got this error upon trying to log on to counterwallet.co.
Then I picked one of 3 servers and went directly to cw03.counterwallet.co.
That allowed me to log in without issues.
I don't know why is this problem happening today (maybe patches are being deployed or something like that) but if anyone encounters this today you can try cw03 (or cw01, cw02).
