Everyone,

Our site totalhash.cymru.com experienced a DDOS hit and caused our main
route to be null routed by our upstream provider. Things are coming online
but the IP that is being attacked will remain down for the time being.
Reply to this thread with any questions.

Thanks,
Scott

Starting around 7:17 am EST, we lost our IPv4 & IPv6  BGP connections to
Cymru. We have two connections in both IPv4 and IPv6 on both of our two
routers. On each router one connection is stuck in active, the other
providing 0 prefixes. I can’t get to http://www.team-cymru.org from
either work or home. Anyone know what’s up?
