TATA problems?

We seem to be having some problems with our tata links - first seen in EU about 45 minutes ago, now we're seeing problems in NA. I'm focused on DNS, so I'm seeing a lot of timeouts/servfails, but our networking folks are talking about links dropping. Anyone else seeing oddness on the NA Internet right now? http://downrightnow.com/ confirms - something is up. cheers, t.
