Twitter had some problems Monday morning — starting just before noon ET, clicking links within tweets didn’t work, and for many people, images wouldn’t load throughout their timelines. It took a little less than an hour for most parts of the site to start working again.
During the partial outage, trying to click a link showed only an error message that said “your current API plan does not include access to this endpoint.” People also seemed to get the error when visiting the site in Incognito mode or if they weren’t logged in.
