When Facebook Inc.’s platforms went down early on Oct. 4, the online tracker Downdetector was among the first places users looked to find out what was happening.

Downdetector, which uses crowdsourcing to track outages, recognized Facebook’s problems were dramatically different than a typical outage. Its system automatically released a notification, including a tweet, informing the internet of the disruption.
