Thousands of Twitter users across th UK are reporting problems accessing the social media platform and its tools.
The company has confirmed it is experiencing problems which seem focused on the south of the UK, parts of the Midlands and areas of Wales.

People are receiving the message: "Something is technically wrong. Thanks for noticing - we're going to fix it up and have things back to normal soon", reports WalesOnline .
In some locations, users can still access Twitter.com, but may not be able to view direct messages, or may have trouble adding images, videos and polls to tweets.
People have also complained of not being able to access the twitter service Tweetdeck, which usually allows users to schedule tweets and perform advanced searches.
According to outage monitoring website Outage.report, more than 4,000 people have reported issues.
The social network acknowledged the problem on their Twitter Support account this morning.
A spokesperson tweeted: "We've been experiencing outages across Twitter and TweetDeck.
"You might have had trouble Tweeting, getting notifications, or viewing DMs. We're currently working on a fix, and should be back to normal soon."
