X appears to be back up and running for many, but we are still not sure what may have caused this outage in the first place.

As we said earlier, previous instances of the platform going down have often been linked to wider outages – such as one impacting Cloudflare in November.

We have approached X for comment, but such requests to its main press email address are often met with an automated reply – which for some time was a poo emoji – or silence.

Elon Musk has, in the past, posted about the cause of notable X outages. But he doesn’t appear to have addressed this one so far.

In the past few minutes, an engineer who works for Musk has posted a well-known GIF of Elmo with hands raised in the air, surrounded by fire.

An hour earlier the same engineer, Christopher Stanley, posted the word “testing”.

It’s a mixed picture for X users, with some still seeing signs of the platform struggling.

It’s always tricky to know when an outage might be completely over, but the number of Downdetector reports of problems at X are much lower than their peak earlier on.

With that, we’re now bringing our live coverage to an end.
