Routing via Level3

I think it's the same site, it did move, but the slowdown in ping was more recent than that. There are rumours (not confirmed) that Level3 have/had some network problems. Traffic from New York to San Diego was also going via Washington/Atlanta/Dallas.

Hi

We have not changed anything our end as it is outside of our peering network and it just up to the transit providers, in this case, Level3.

Was it exactly the same destination as before (It may sound like a stupid question but routing is very strange).

No traceroutes available for the NY route. The Frankfurt-Washington hop seems extraordinarily long.

Hi

What is the server? Also do you have any traceroutes showing this?

Had a couple of p[eople living in new york complaining regarding this also.
Is this for good?

Has routing changed? Connections to a service I use on the West Coast USA now seem to route via Frankfurt and Washington rather than London and New York. Ping times are now nearly 200ms rather than 80ms.
