[outages] AT&T "over saturation" Southwest USA

[Bryan Inks]

Update 1:13pm Pacific

Traffic appears to be normalizing across the area. I'm seeing 50-100ms and no drops at this moment on affected nodes.

My internal testing doesn't show that.

I just received word from Internap that they are the target of a DDoS as well. I'm still seeing the same symptoms as reported across all of my upstream providers that hit the ATT network.

We were told by our provider that it was a Ddos as well.  They said it was mitigated as of about thirty minutes ago.

Passing along the good word from /r/networking

"For anyone in the southwest US (specifically anything that goes through southern California, ATT is experiencing an "over saturation" on their network.
It appears to be affecting every handoff in the area.
Problem nodes: 12.122.x.x
Symptoms include dropped packets and 400+ms latency.
Internap, Cogent, and Level3 have confirmed tickets opened with ATT NOC.
Update: ATT reports it as a DDoS attack that is causing the issue. They are working to mitigate."

I'm outside the affected area so I don't have anything technical to add and wasn't sure if appropriate for me to notify the list.
