A year or so ago I did some research and testing of the variety of website uptime monitoring services out there. Sure any half-decent host does this as well, but sometimes a server only goes down externally and sometimes it doesn’t trigger their monitors. I also did this because I wanted to get a clear picture of just how much downtime a site might have.
Sites do go down, even if just for schedule maintenance. I wanted to see just how reliable my hosts were. Some of my hosting is supposed to be much more reliable than other hosts, and I wanted to see if I was getting what I was paying for.
When searching the first thing I realized were most all of the free or free trial offers were limited to the point of being useless. The next thing I noticed was that the paid options seemed rather expensive.
But then I came across Uptime Robot. They provided monitoring up to 50 sites – for free. They offer a number of configuration options, as well as uptime checking every five minutes which is much better than the 10-30 minutes other services offer. (I mean, really. If a service is only going to check every 30 minutes, that’s pretty much worthless. I’m going to have received a call by then.)
I’ve exchanged some emails with Uptime Robot. They helped me discover a problem with one host’s email, and they also implemented a feature I requested. They’ve been monitoring away on about a dozen sites of mine for about a year now, and they’ve done a very good job at it.
