Find a way to notify if rodan-production is down

[timothydereuse]

If rodan-production goes down for longer than, say, fifteen minutes (however long it should go down in the normal course of updating it or rebooting it), I and everyone else working on maintaining Rodan should get an email about it (or, better, we should get a notification in our Slack about it).

All we need is something that can run on one of our servers and ping rodan2.simssa.ca at regular intervals, and send some kind of message if it doesn't get the expected response for several pings in a row.

I got curious and trying to ping rodan2.simssa.ca I received Request Timeouts and all web packages were lost. I tried on both on my local computer and our staging server. rodan2.simssa.ca is working too. Does anyone know why this is the case? I'm not that familiar with networks and such but would love to learn more!
