Apparently some facebook interface decided to DDOS the site a little over an hour ago.

It's not overwhelming the network, just an absolutely ridiculous number of requests.

I've solved it by instituting a global rate limit. It should be high enough to not affect anyone actually using the server.

Basic gist is that any more than 10 requests a second gets a 429 error (Too Many Requests, like all error codes with this site it'll give you a cute cat picture specific to that error). This is purely per second, so if you see that error at any point the time it takes you to refresh again the limit will already be reset.
