Eugen Rochkomastodon.social, mastodon.online and joinmastodon.org were hit by a DDoS yesterday, thankfully joinmastodon.org was already behind Fastly so it didn't have any impact on it. We've now moved mastodon.online behind Fastly and will do the same with mastodon.social soon.
Mr. Funk E. Dude 🍑💨@Gargron is there an expected downtime when switching to Fastly??
Renaud Chaput@Mrfunkedude @Gargron there should be no downtime if we do it properly, which is the plan 😉 There was no downtime when I moved mastodon.online earlier today.
