wow. how would one even fix this without deliberate downtime? you'd have to deploy and hope that the frontend will make it through CDNs to reduce pressure, right?

Yeah frontend retry DDoS is not a great situation to get in. I've tripped it in a test env before with a websocket app (erroneous retries caused certain clients to open the WS over and over and break the server).

Do you know how many current Twitter engineers are on H1B? Is this based on some data, or just speculation?

Around 300. https://www.vice.com/en/article/n7z5px/twitter-employees-on-...

I think that may be outdated. Searching at https://www.uscis.gov/tools/reports-and-studies/h-1b-employe... yields around 60 applications in 2023 (but note that I'm not sure how things are counted given that H-1B is valid for 3 years).

Twitter operates its own datacenters.

"Twitter and AWS signed a five-and-a-half-year contract in 2020, which AWS is not willing to renegotiate." https://gritdaily.com/twitter-owes-aws-millions/

Twitter.com and the associated user-facing services do not run on AWS.

One weekend Russia attacks Russia, next weekend Twitter attacks Twitter.

unlike what others have said, Twitter was very useful during the saturday mutiny in Russia. I follow a lot of people who supplied updates and thoughts.

It withstands being one of the first link on HN, and it still loads comfortably. For a personal website, that's a great performance.

HN traffic is not nearly the DDOS people make it out to be. I made it to spot #2 once and that was a few dozen hits per second at most. Maybe not something to serve with wordpress from a raspberry pi, but hardly apocalyptic levels of traffic.

Wordpress on a raspberry pi will handle static, properly cached content just fine.

This is interesting. Judging from the screenshot, a huge amount of GET /TweetDetail is generated which triggers some rate limiting, as shown by the 429. If this is indeed due to the recent decision to enforce authentication for all API calls, it means the curlprit may actually be the API gateway or something similar downstream. Also, this behavior seem to never stop, which isn't what one would expect from an exponent…

"curlprit" for too many GET's causing a 429 is just the perfect typo.

Meanwhile, I can see this very Mastadon post with no login just fine. And the interface is not trying to assault me. It loads quick. ...Seems like a better product than Twitter for a public feed.

On Mastodon simply discussing certain topics will get you banned, and instances that don't ban those users get defederated.

I prefer Twitter in the sense that it's more laissez faire in terms of what kinds of speech get you banned.

He’s the richest man in the world, and a bully narcissist who punches down as a hobby. He’s not the unpopular ugly kid, he’s the one who attacks those kinds of kids. And he certainly doesn’t need you to defend him.
