Please be advised we have received the following notification from O2 regarding planned maintenance impacting their PSMS platform on the below date and time.
Change Window: 03/08/2026 21:30 (pm UK time) – 07/08/2026 06:00 (am UK time)
What are we doing: Upgrade work is taking place which could result in a momentary disconnection before an automatic re-connection of binds.
The upgrade will be carried out in stages during the above time period and will be being carried out overnight only on each day. Please note that not all stages will result in a service outage and we anticipate that any connection drops will occur on the night of 3rd August 2026.
Please be assured that we are doing everything we can to ensure the upgrade runs as smoothly as possible for our partners and to minimise any disruption throughout the process.
Impact: There will be an outage in the form of a very brief connection drop during the maintenance window. Unfortunately we cannot give an exact time during this maintenance window for the drop(s) but binds should re-connect straight away. Messages are not expected to be lost.
What can we tell you about this: The activity will take place throughout the maintenance window. There will be a brief drop and reconnection during the maintenance window. This could impact both PSMS MO and PSMS MT submits as well as any Bulk A2P and P2A messages. Direct Billing is not impacted by this work although it may impact any receipt messages that are sent via PSMS MT.
Please note, every effort will be made to mitigate the effect on our customers experience during the work but a service outage is expected.
If you have any questions please contact your account manager
