[NCLUG] AT&T: 12.244.71 subnet causing lag

[Brian Stanback]

Corey,

I have seen the same behavior all yesterday - I haven't checked today yet.
I was seeing latency of ~500-600ms to places like google, yahoo, frii. I
did a traceroute, and noticed one of their routers/switches was slow (not
sure which one it was though) I was also seeing somewhere in the
neighborhood of 20-25 hops to anywhere on the internet and over half of
those were on the att network.

I am hoping this is temporary. I was seeing ping times of around 40-50ms
to google, etc. the afternoon service was turned on.
