Dear Valued Customer,

Please be advised that O2 engineers have cancelled this planned works and moved it to the 17th June 2025. 

All corporate customer APNs are built on two back-end nodes within O2s network - end devices initiate data sessions via one of these two back-end nodes.

One back-end node will be totally unaffected by this planned work and any data sessions initiated via this back-end node will remain in place.

The migration window is:

Start Time: 11/06/2025 10:00

End Time: 12/06/2025 02:00

If devices have initiated data sessions via the back-end node that is being upgraded their data sessions will be terminated and the devices will have to re-initiate new data sessions via the back-end node that is not impacted by this planned work.

In most cases, devices will automatically reconnect or attempt to establish a new session.

However, depending on individual device configurations or software, some devices may require a manual restart.

APNs impacted by this maintenance are detailed below:

arkessa.com

newcastle.uk.g4s.com

tesco.4g.verizon.com (after midnight)

The maintenance will take place during the times specified in BST(British Summer Time)

We appreciate your continued custom and thank you for your understanding.
