200 - 2TB Chassis 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 CHESSINGTON region to introduce more capacity.
Service disruption will start at 01:00 when the router will be re-booted.
This should take about 15 minutes, but may extend to 45 minutes if there is a problem.
There will be a further 20 minute service disruption when we upgrade individual cards, again this could extend to 50 minutes if there\'s a problem.
We plan to be finished by 04:00 , however if we encounter additional problems, service outage could extend to 06:00
