I had signed up not too long ago with a site monitoring service hoping to create proof of our uptime records. I submitted 3 of our sites all on the same server
to be monitored --- but for some strange reason --- they are all producing different uptime percentages because of some "HTTP error" it picks up and reports as "downtime" at random times about 1 per every other month per site.
The exact error that is reported to me is:
But I can't seem to find what actually causes this. Any ideas or is this out of my control? Will also consider suggestions on using another server monitoring service. Maybe a poll is in order as Nadabrahma suggested here.
