Ever since I started using it, and to this day, I've felt like Gmail is wonderful, magical, useful, intuitive ... In short, it's basically the best email service I've ever used. Most people who have made the switch from AOL, Hotmail, Yahoo, etc. would agree. Not to mention how, for most people, AIM is a thing of the past, because we all use Gchat for our "off-record," real time correspondence these days. The best part of it all is that you can rely on Gmail. It really never glitches out. Oh, wait. That's not true.
Yesterday, a Gmail outage lasted for over an hour and affected "less than 10 percent" of Gmail's user base, or approximately 33.2 million people! That's the official word from Google, but I wouldn't be surprised if the actual number of people affected was higher. I experienced the outage for at least 45 minutes. Definitely a pain, especially when you're trying to use all the other integrated services -- like Google Calendar, Docs, etc.
