On Wednesday, Twitter CEO Elon Musk said that Twitter should "feel faster" due to "significant backend server architecture changes" being rolled out.

It did not feel faster for many users. Instead, thousands complained that the site isn't working for them, especially on desktop.

Downdetector shows a spike of complaints about a Twitter outage which has mostly subsided by now, with 82 percent of users reporting that Twitter's website wasn't working properly. (Editor's note: Downdetector is owned by Mashable's parent company, Ziff Davis).

Some users complained about not being able to send tweets or retweets, while others were simply greeted with an error message when trying to access the site.

Twitter's official support account made no mention of the outage; in fact, it hasn't tweeted since Christmas.

When asked about the outages, Musk tweeted "works for me." Well, we guess that's sorted then.

Musk has tweeted about performing backend upgrades at Twitter on several occasions after taking over the social media site, saying the changes should make the site faster. Last week, Musk tweeted about Twitter still working, even after he disconnected "one of the more sensitive server racks." Maybe it's time to reconnect that rack?
