Any of this sound familiar?
- You find out your site has been down for over an hour … from cranky people on Twitter and Facebook.
- What about missing out on that time-sensitive request for proposal, because your email server wasn’t pulling new mail?
- Is your payment processer down right now and you don’t have a clue, because the rest of your site is up and looks fine, but no one can buy?
All of that has happened to me more than once over the last 15 years, especially before we took control of our own hosting. But even then, sometimes things go wrong, and you simply have no idea.
For example, a couple weeks ago we discovered that a site map on Copyblogger had been completely borked for who knows how long. It had been created back in 2008, and somewhere along the line it failed, causing significant damage to our search rankings on Bing.
How did we find out about it and fix it? Site Sensor, the new website monitoring service we created to sniff out these very kind of problems.
