Brazil's X ban is sending lots of people to Bluesky

Servers are holding up so far. Somewhere been 800k-1mm signups (need to check backend). Fortunately we were overprovisioned. If we hit 4mm new signups then things should get interesting.

edit: we did have some degradations (user handles entering an invalid state, firehose crashed a couple times, image servers are giving bad load latencies randomly) but we managed to avoid a full outage.

(in case I look like a crazy person, hn threads got merged so see my other comment which was a copy & update of this)
