All your internets r working fine

by jasonn | August 25, 2008 - 4:42pm

Many national ISPs designed their technical support in such a way to deflect competent users from reporting legitimate network failures. I should mention that I'm pretty sure they know about their problems. So, assuming they want my input is a tad egotistical. Trust me, whomever your ISP is they don't want to hear from you about their network problems.

Here's their problem:

This is from my home (cable) internet connection to rr.com, which is their website. I thought it was a good example of where the problems lie.

Below is a MTR to yahoo.com.

After a mere 4 phone calls, someone finally gave me the tech support email. I sent this information to them. It will be interesting to see if they respond. Interesting, like shocking if they do something about it.

And, a bit more MTR reveals a very solid and consistent packet drop.

Interestingly, there's also useful information from an outside traceroute (MTR) from a system on Comcast's network.

Just for fun, I ran a few thousand seconds of MTR.
