The British Library has confirmed to The Register that it was a "cyber incident" is the root of the "major" multi-day IT outage.

The Social Media mouthpiece for the Library reported issues in the early morning of the 28th of October, stating that the Library's website and services offered at St Pancras, the St Pancras site in central London, such as Wi-Fi accessibility, were affected.

The British Library said in a blog post on the X page that they anticipated that the issue would persist over "the next few days."

The subsequent updates have confirmed that the phones and services on-site at both St Pancras and Yorkshire were not working, and the Library's website still needs to be made available at the time of writing.

The British Library is experiencing a major outage in technology due to an attack on its network," it told The Register.

"This affects the online services and systems such as our website online services like the Reading Rooms. We are looking into the issue with the assistance of the NCSC National Cyber Security Centre (NCSC) as well as cybersecurity experts.

"We appreciate the understanding and support that we've received from clients, staff as well as our business partners.

"The Library's sites remain fully open to the public, and details on the services that remain available can be found via @britishlibrary on X."

According to the source, the issue began around 07:30 on the 28th of October and was the first place due to "major issues" with its VMware servers "that have made nearly all their VMs unavailable."

We contacted the British Library to confirm this information and further clarify the details of the security breach; however, they have not replied.

The famous London library, which is home to the Magna Carta, is still accessible to the public, but it is only accepting cash in the event of ongoing technological problems.

Reading rooms are available for study on a personal basis; however, people will have to be able to work offline or utilize other options for connectivity, like mobile hotspots.

The other services are still available, however, in a limited capacity. Customers can pick up orders, but only on orders made prior to the 26th of October. There is a "very limited" ordering of things to collect on St Pancras. St Pancras site.

"We are working to resolve these issues as a matter of urgency and will be updating users via our social media channels," the post stated.
