Twitter experienced multiple issues as only one person was handling the platform's API, causing links and images to stop loading and users having trouble accessing TweetDeck.
The company made an internal change as part of a project to shut down free access to the Twitter API, which resulted in unintended consequences and cascading consequences inside the company.
Twitter's recent change has ended the existence of third-party clients and drastically limited the ability of outside researchers to study the network.
Elon Musk commented on the recent Twitter outage, stating that a small API change had massive ramifications and that the code stack needs a complete rewrite.
