We are aware that there is a global Microsoft issue that is currently impacting our systems at the moment, therefore you may experience delays accessing some TalkTalk sites. The team are working hard to get things back up and running as quickly as we can.
Update 5:30 PM -
This is a global incident caused by a software update from cybersecurity firm Crowdstrike impacting customers and business on Microsoft products. This is not caused by a cyber attack or security incident. A fix is being deployed but will take time to take effect. We hope to be back up and running as soon as possible.
