Ha - I probably shouldn't laugh, but I always smile when I see that fly up the screen - even when it's my job to fix it.

PROBLEM

Any running configs about Main office and Branch ???

I'm assuming this is resolved by now, but if you ever see it again, check the CEF table and see if it's all torqued up. That's been the culprit of the last few routing loops I've seen.

turns out it was a telco line issue, we are all set now. What i dont get is that when a line goes down like that traceroute usally shows a timeout. Must have been some goofy routing issues with the telco.

They're not going to tell you exactly what happened. Better for them that you assume it was an "unavoidable technical issue". It's a liability issue

But yeah, they screwed up...probably fat fingered a configuration.
