Internet Connectivity Monitoring

[Alex Dehaini]

We monitor our upstream provider core routers. Basically, we monitor every
physical device between us and them. So, if any device goes down, we can
tell where the problem is originating from.
Secondly, if you have a co-located server outside your network, you can
monitor that as well.
