Twitter outage December 2014 due to ISO8601 year confusion

The single character G instead of Y took down Twitter’s API today.

As seen on HN and see also The Guardian:

That bug caused users of the network’s Android app and mobile website to be logged out, without any ability to log back in until it was fixed at 5.25am. It also led a number of visual flaws, such as showing TweetDeck users that tweets were posted 365 days ago.
