I'm seeing issues with traceroutes dying at Sprint in London, too.

From our site here in the UK (transit from NTL Telewest Business) I can't reach cisco.com (but I know cisco.com is up - I can reach it from elsewhere). Apparently customers of XS4ALL in the Netherlands are seeing similar behaviour.

Hi,

We are seeing traffic getting dropped between our Cogent and Sprint connect DC's. One of them is getting shutdown, so we just have a Cogent link there :| Anyone seeing anything similar?
