[Connectivity] Slow Route and Bad RDNS

Over the past week accessing the Google-brand of sites, including youtube.com. Routes have been pretty consisting reporting 15+ hops. Anyone else experiencing slowness?

W.I.W., here's a trace to that server from Northern N.J. I don't perceive any "slowness" here.

Tracing route to pw-in-f100.1e100.net [74.125.53.100]

It is unclear why the Google CDN is responding with a server that is not local to you. We will report it to Google
SEE ANSWER IN MY NEXT POST

NOTE: Number of hops has little impact on latency with today's router technology. Speed of light / physical distance does however.

Is there an issue with RDNS? Based on your traceroute the hops within our network are populated.

Thanks

Try the same traceroute to www.google.com (not google.com)?

• google.com translates to a non-localized IP address.
• www.google.com and other service names should localize better

Looks a lot better when going to www.google.com

Thanks for the clarification.
