Hasn't fallen over, no, but loads of issues have been impacting users.
I lost all my Tweets for a while, and people are losing and re-gaining followers. Donald Trump at one point managed to gain millions of followers more in a few seconds, then lost them (at the time when a lot of people pointed out that they weren't following him).
There are issues with image hosting, managing your profile, logging back in with 2FA and probably loads more problems - not least lagging, and the timeline showing things in the wrong order and repeating Tweets.
Then, from a financial point of view, there's the lack of advertisers and the ads now are the type of ads you see way down the page on a local newspaper site with the 'you won't believe this hack to turn lights on and off, and every home has them'.
And do you seriously believe Hunter Biden travelled across America to drop a laptop off with a blind man who then somehow got in touch with Rudy Giuliani or Tucker Carlson (can't remember who) - who then somehow managed to be totally unable to produce any evidence, claiming it got lost in the post or something ridiculous?
