AT&T-twtelecom LA issue

Hello.

We are experiencing traffic issues between AT&T and twtelecom between SF and LA (5-7% dropped and out-of-order packets, increased latency RTT).
Issue occurs only during business hours pacific time. We are on the AT&T enterprise side of the equation.

My personal guess is oversubscribed peering, but what do I know?

If anyone from att or twtelecom sees this, help!
