One of the things I remember from an internship there a few years ago, Facebook does its main "push" of new code to its server farms on Tuesdays around 5pm (i.e. around this time). It would be interesting to read a postmortem on what brought down the most visited site on the world—was it an image staging issue? A latent bug in the product? A badly configured setting? A malicious attack? A network problem? Hopefully Facebook Eng will do a write-up on the root cause!
- seldo 13y agoI thought Facebook did daily/continuous pushes? Or did that end?
- achalv 13y agoStuff is pushed every day, but the biggest chunks are pushed on Tuesdays. Source: Friend who interned at FB.
- mrmaddog 13y agoExactly. You can find more information here: https://developers.facebook.com/support/beta-tier/ https://developers.facebook.com/support/beta-tier/ "Every week, usually on Sunday evenings, we stage our weekly push, which happens on Tuesday evenings, on the beta tier. This provides ourselves and developers 48 hours to test and find bugs before the build hits production. After Tuesday, while the beta tier is continuously updated with hotfix patches which are queued up for the daily hotfix release, the production tier is updated with the hotfix push in the evenings, Pacific Standard Time"
- achalv 13y agoAh, makes sense. Thanks!

- guiomie 13y agoI remember once reading or seeing a video bragging Facebook didn't have QA, maybe its time.
