30% packet loss between cox.net and hetzner.de, possibly at tinet.net
From: "Constantine A. Murenin" <mureninc () gmail com>

Hello,

There has been at least a 25% packet loss between hetzner.de and cox.net 
in the last couple of hours.

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?

The huge packet loss even extends to the regular cox.net web-site, it seems:
