"Internet" Outages of 2 minutes or so
Posted on 2011-10-31
I have some fairly knowledgeable users who are reporting "internet" outages of 2 minutes or so. That is, they can't open web pages and can't get email during those times.
They have been logging when these observations occur.
I've been running a probe that requires 3 lost pings in a row to launch a traceroute. When something really breaks, the traceroute shows where.
But, I've not captured a bad traceroute, even if one was triggered by 3 lost pings, during the outages reported.
So now I'm wondering if someting else might be going on.
I'm monitoring port errors on the internet connections.
I'm wondering if email or http specifically might be subject to a failure or interruption and how to automatically test for that?
