It is possible that Twitter engineers unintentionally created the disruptions while making major changes to its systems.
Twitter has been making changes to its API in recent weeks in an attempt to generate more revenue. The company announced recently that it would largely cut its free API support, effectively killing off third-party services that rely on it, such as third-party Twitter clients.
The company had promised that a new service would be “coming very soon” in a tweet posted on 26 February from its account focused on developers. It may be that the latest problems are the result of the long-awaited introduction of that new API.
Twitter support posted about the problem.
Things should now be working as normal. Thanks for sticking with us! https://t.co/JXTllrv0k0

As the issues continued, new owner, Elon Musk tweeted “this platform is so brittle (sigh). Will be fixed shortly”.
Twitter may have brought that API access to an end without announcing the change, and in so doing, breaking all of its own linked systems that rely on access to that API.
