I don't really understand this architecture, but I thought Bluesky was distributed like Mastodon? How can it have an outage?

> What I had missed is that we deployed a new internal service last week that sent less than three GetPostRecord requests per second, but it did sometimes send batches of 15-20 thousand URIs at a time. Typically, we'd probably be doing between 1-50 post lookups per request.

That’ll do it.

> The timing of these log spikes lined up with drops in user-facing traffic, which makes sense. Our data plane heavily uses memcached to keep load off our main Scylla database, and if we're exhausting ports, that's a huge problem.

I expect this is common.

Lite Blue on a dark Blue background. That is a new one, I have seen grey text on lite grey, but blue on blue ?

The article does work in lynx, at least I can read it.

All support to other decentralizers but nothing never goes down.

1000x redundancy makes it vanishingly unlikely. Although I know we're due for a pole shift so all bets are off I suppose.
