Attempting to ssh mwmaint1002.eqiad.wmnet through bast4002.wikimedia.org results in the error "fork failed: Resource temporarily unavailable", followed by 50-100 lines all reading ssh_exchange_identification: Connection closed by remote host.
This might be some kind of loss of access following the move to the new bastion recently, I'm not sure. The timing matches up though.
My name on prod is foks. The same errors are happening for @Jalexander (not sure what he uses on prod).
(I am really not sure which project this belongs in, so sorry if this is in the wrong place.)
