This is an expert from a Gmail Blog Post re: the recent gmail outage:
Unexpected side effects of some new code that tries to keep data geographically close to its owner caused another data center in Europe to become overloaded, and that caused cascading problems from one data center to another. It took us about an hour to get it all back under control.
This sounds exactly like the types of bugs I create. The fact that Google makes these sorts of mistakes, even though they do a lot more testing and have bigger teams, etc; makes me feel good about my programming skills.
Update October 2010: These instructions are no longer valid. Take a look at voyageurs60’s comment.
If you’ve ever tried to delete more than 20 contacts in gmail, you might have noticed an error message informing you that you’re only allowed to delete 20 contacts at a time.
I don’t really think of Google as a company that puts abitrary limits on features. Who knows why they decided upon this limit.
Suppose you’ve accidentally quadrupled your contacts list in some sort of import mishap and you just want to start over. There’s a fairly simple – if somewhat non-intuitive – workaround for this. Click the “older version” link it the top navigation bar (http://mail.google.com/mail/?ui=1). This will allow you access to the old contacts list interface.
1) click “all contacts” tab
2) scroll down to the bottom, select “all” (no idea why this option is not at the top of the interface)
