Twitter Pager Rotation.

It dawned on me that if I were working for Twitter that I would just assume the service is down unless told otherwise.

This lead to the conclusion that one should invert monitoring to send off a notification when Twitter is online

Seriously. I like those guys but this is getting kind of embarrassing.

As someone interested in distributed, scalable, and reliable web services, I think I might stop using it out of protest.

Things could be worse though – they could be using Hadoop! :-)
