UK commuters are in for a bleak morning on an otherwise sunny Friday after Southern, Thameslink, Gatwick Express and Great Northern operator Govia issued a travel warning across its network.
Govia posted this on social media: “We are currently experiencing widespread IT issues across our entire network.
“Our IT teams are actively investigating to determine the root cause of the problem.
“We are unable to access driver diagrams at certain locations, leading to potential short-notice cancellations, particularly on the Thameslink and Great Northern networks.
“Additionally, other key systems, including our real-time customer information platforms, are also affected.
“We will provide additional updates when we can. In the meantime, please regularly check your journey before you travel.”
An apparent “flawed anti-viral update” at Microsoft HQ is the root of the problem.
A cloud services outage overnight initially caused chaos in the US overnight with emergency lines reportedly down, only for massive IT problems to hit Australia and now Europe.
Microsoft announced on its social media accounts that it was "investigating an issue impacting users' ability to access various Microsoft 365 apps and services".
