I’d never have thought that the recent recession would have an effect on computer uptime, but one blog claims that is the case and they have good stats to verify that.
I have in the past used monitoring services when this blog had outages in December, but sometimes they reported false outages. So for my blogs which I visited daily, it was quite unnecessary. For sites that don’t require much maintenance, though, having a monitoring service could be useful especially if you’re doing Internet Marketing, and have dozens of sites.
