Tried contacting hetzner.de, but they said it's not on their network. This has already happened a couple of days ago, too (strangely, on April 1), but then was good for the rest of the week -- no problems whatsoever. I wouldn't really care about this, if not for ssh: it just doesn't work on such huge loss. No other routes or networks seem affected. Any advice?Doesnt looks like tinet for me.
Might have been eurorings.net, as your Amazon EC2 to Hetzner
traceroute seemed to suggest?
This loss was apparent even with their own main websites:
cox.net from a hetzner.de node:
