2777 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  4. Edge Data Consistency advanced

    After a price change you issue a CDN purge and every point of presence returns 200. Twenty minutes later customers in one region still see the old price, and a hard refresh fixes it for some of them. Where do you look and in what order?

  7. Edge Functions advanced

    Shortly before 10:00 UTC on 8 June 2021 a Fastly customer pushed a valid configuration change and about 85% of the network began returning errors. The bug had shipped on 12 May and lay dormant. Detection took about a minute and 95% of the network was recovered within 49 minutes. What class of failure is this?
