TIMOS and MSE card upgrade
We need to make a change to BT\'s UK Core Network that will unfortunately impact your services.
A list of your impacted services is attached;
(This could take up to 48 hours)
We\'re upgrading some 21C network hardware and software in the WASHINGTON region. This involves a software upgrade and some hardware changes on the device in a single night.
The outage to all customers will be after 01:00 for approx. 15 minutes whilst the device is rebooted. This could extend to 60 minutes if roll back is required to reboot to the old code.
Customers may experience a second outage of about 60 minutes while we upgrade the interface card connecting their circuit. This could be extended to 2 hours if roll back is required.
We plan to be finished by 04:00 , however if we encounter additional problems, service outage could extend to 06:00
