I see a giant circle around like 10 sentences, none of which feel like the sum up twitter in any way? After some consideration I guess maybe you're referring to "What's happening?"
it's a 429 error, so the developer who posted this is an idiot. they're not even wrong. the 429 doesn't even touch twitter's infrastructure. the HTTPS TLS terminates at a Google VM, which gets relayed depending on the VIP used to hit it, but the traffic never gets past that Google VM. This is literally /HOW/ companies deal with DDOS.
