Message Exchange Service Notification - Production Planned Maintenance Jan 24, 2026 08:00-11:00 GMT
Dear Message Exchange Admin,
What is this notification about?
This notice is to advise you of planned maintenance within the Production environment for the Message Exchange Market Service. During the maintenance, a new SSL Certificate will be applied to all SSL connections and digital signing of all messages sent from the Production Message Exchange service.
When is the maintenance scheduled?
Saturday 24th January 2026 @08:00 (UK) till 11:00 (UK).
How does it impact me?
The SSL certificate is used for The Message Exchange (TMEL) digital signature in the SOAP envelope of the message, and for the HTTPS/SSL handshake. Without the new SSL certificate, messages through your gateway solution to The Message Exchange’s Production environment may fail.
Please note that during the scheduled maintenance window, users will not be able to access the Message Exchange Service in Production.
What action must I take?
The SSL certificate was sent with our email dated 19th Janaury 2026 and can also be obtained via the LIMOSS service desk.
Customers are advised that the SSL certificate should be (if relevant) added to any gateway solution connecting to The Message Exchange Production environment, for both your SSL connection and digital signing validation anytime between now and 00:01 on 3rd February.
If you have a system that only allows you to replace the certificate, the new certificate will be active as from Saturday 24th January, so you will have from then until the current one expires on the 2nd Feb 2026 at 23:59:59 2026 GMT to replace it.
Next update
A final reminder will be issued Wednesday 28th January.
