Problems with AT&T

Anybody here seeing problems with AS7018 ?

Thanks

I peer with AT&T's hosting AS, AS4264, which uses AS7018 for all of its
transit- not seeing any issues from here. What've you got going on?

Folks have been reporting various weird problems with AS7018 for the last
2-3 weeks. It seems to affect some types of packets, but not other types
of packets (i.e. you can ping or get some web pages, but not other web
pages). If you report it to AT&T, they seem to get it fixed; but then
the problems re-appear a few days later. I'm guessing that packet size
is relevant, but I haven't spent much time trying to troubleshoot it.

isn't at&t heavily MPLSed? maybe something to do with mpls tunnels, or diff-serv marking?
