Dear Authorised Contact

What is this notification about?
This notice is to advise you of planned maintenance within the Production environment which will affect the LIMOSS Portal, LIMOSS SDE, LIMOSS Devolved Admin Portal (DAP), LIMOSS API Gateway and all APIs provided via the Gateway as the certificates are being renewed.

When is the maintenance scheduled?
Tuesday 17th June 2025 between 19:00 and 22:00 (UK).

How does it impact me?
During the maintenance window, LIMOSS Portal, LIMOSS SDE, LIMOSS DAP, LIMOSS API Gateway and all APIs provided via the Gateway will be unavailable to all users.

LIMOSS SSO authentication, and access to other services such as DDM are not expected to be impacted by this outage.

What action must I take?
All organisations are requested to:
1. Inform relevant colleagues that this maintenance is taking place and that users may experience problems
with the services listed above during the stated date and times.
2. As our certificate is being updated for the API Gateway, you may need to update your record of it.
see point 4 below.
3. During this maintenance window, users experiencing any problems calling APIs are advised to wait until
the outage has completed and to retry their request.
4. After the maintenance has completed, we advise all API subscribers and API publishers to test call an API via the PROD LIMOSS API Gateway
o API publishers are advised to check that their app can correctly validate the JSON Web Token (JWT)
received from the API Gateway.
o If the call is successful, no further action is required.
o If the call fails, please update the Public key which can be found here
https://api.londonmarketgroup.co.uk/discovery/keys or alternatively contact the LIMOSS Service Desk.
