Recently we've been having a lot of problems with Gmail at work (we use Google Apps) and it's good to find out that I'm not the only one.
One thing about email problems is that I get notified very quickly. My users would call me up the instant anything goes wrong and demand me to fix it. Unfortunately, when the email is hosted elsewhere, there's very little that I can do. I tried to get my boss to pay for the Premier Edition with uptime guarantee, but since we have a lot of users, the cost is just way too high. I hope one day Google will have a lower priced edition with uptime guarantee but without the other fancy stuff.
The Gmail guys really work out their problems very quickly though. So I would always tell my users that I'm working on a fix, and after a few hours they'll call me back and tell me that they can use their email again!
Today is also H.M. the Queen of Thailand's Birthday and also Mother's Day. Happy Mother's Day!
