We experienced packet loss to the Atlanta data center. Things are back to normal now and we are still investigating the cause.

Mike

Just the reason I moved to Fremont, CA less than a month ago.

I had some issues and opened a ticket.

As of right now everything looks 10x better then it was.

Please update if the problem solved completely.
also I wonder if this is something to do with my old ticket - 42079 regarding that some of my client can't access the server.

Thanks!

This was a transient network flooding attack. Unfortunately, it came and went before we were able to identify the target. It was not a problem with this data center's network. In the coming weeks we'll be upgrading our uplink to a gigabit link, which will our machines in Atlanta that much more resistant to this type of activity.

Have the network issues returned?

I'm noticing lots of packet loss getting to my Linode host:

--- host83.linode.com ping statistics ---
54 packets transmitted, 19 packets received, 64% packet loss
round-trip min/avg/max/stddev = 250.624/266.534/288.880/14.419 ms

Especially getting from atl-core-a-g3-1.gnax.net to l3-atl-18.gnax.net.

Yes, I was basically disconnected from my Atlanta node for some time tonight. Seems to be better now though....

Yes, as soon as I posted, the situation changed:

--- host83.linode.com ping statistics ---
802 packets transmitted, 802 packets received, 0% packet loss
round-trip min/avg/max/stddev = 116.005/120.553/1121.018/51.702 ms

Things are looking good from Our end.

MrRx7... 15 hops _inside_ Cisco? Yowsers! That's a lot of routers. Traffic from my house (in New Jersey) to a server located in Holland is only 14 hops.

Wowsers.
