This is weird to say out loud, but I actually am kinda an expert in rate limiting, so I'm gonna explain some stuff.

About half of incidents in large-scale production systems involve having more requests than you can serve. There are two categories of this kind of incident: 1. Top-Down overload or "Reddit Hug of Death": This is what Bluesky experienced today - suddenly there was a HUGE demand surge and the servers just *couldn't* for a while. This also happens after superbowl ads or when pop stars announce tours or during DDOS attacks.

I started with TC39 just over a year ago. The first day that I went, I was completely terrified. I had been told that the committee was aggressive, could be hostile, and has no understanding of the needs of regular devs. I was one of the first women ever to go (with @fhinkel and @adalex). The feeling of walking into a room of people who are Way Smarter (TM) can be really overwhelmingly negative. I am exceedingly aware of the fact that I'm not a compiler dev - just a regular web app dev.
