Google Chrome random number generator issue
The weirdest thing happened. At least everyone thinks this way until they realize it was just a stupid bug somewhere. This time it was Google Chrome that stopped the show.
We have a small Google Chrome extension that generates an unique ID every time it gets installed. We want our server to be able to tell apart from different installations (and also be able to count them). So we want a unique GUID on each installation but we don't care if there is a duplicate ID one in a million.
For months our application has been working as expected and our randomly generated GUIDs kept getting sent back to us. Everything was going good in an extent that we had a nice little metrics graph implemented to show off for our growth. Then it suddenly stopped one day. Our new installs went flat. Everything was suggesting we just got less installs but the graphs showed no visible decrease in site traffic or server load.
