Considering the hostile takeover of Twitter, the layoffs, lack of leadership and Elon pulling cables out of servers, the platform has been working exceptionally well, at least in my experience. Either it was built like a tank or some of the people working there are extremely competent. To be fair is not like Twitter has never been prone to issues. I'm an old enough user to remember the fail whale and many of the great outages of Twitter's first decade. It didn't became stable until maybe 5 years ago and even recently just prior to Elon coming in they had another hours-long downtime.
