Following the outage today, we are during the course of tonight, commencing at around 10pm, making some changes to the core network routing to bring further stability & resilience online. This may mean a few blips in routing tables as the changes are disseminated and an occasional up-tick in latency as routes converge and stabilise but we expect no downtime or any significant service issues.
UPDATE: the supplier has confirmed the new date, with timings unchanged for this work.
This should not affect any services or connectivity. There may be a brief transient period when routes flap until the routing tables converge again.
Start of maintenance: 25/11/2015 – 00:00 GMT
End of maintenance: 26/11/2015 – 04:00 GMT
Duration of work: Up to 30 minutes during the window
Classification of works: Standard
Description of works: Essential Third Party maintenance
Over the next few days we will be installing a new host link for our adsl backhaul. This should not cause any downtime but you may notice a ppp drop as sessions are balanced across the new links.
This should only cause a few seconds of issues however in some cases it may be that your router needs to be re-booted to reconnect.
If you have any issues please call support in the normal way.
We’ve been advised by Allegro, one of our transit suppliers, of work to be undertaken on one of their core routers in Manchester. This should not mean any loss of service to us or our end-users as we have multiple diverse routes into and out of our data centres — there may be a few moments of route instability during the 45 minute work window until they re-converge and stabilise.
Date of work: 17.09.15
Start time: 00:00 BST
End time: 06:00 BST
Place of work: Manchester
Planned Work: EU3819
Work description: Service migration to a new device
One of the smaller UPS units protecting one of the racks here in the data centre is indicating that the bateries need replacing. These are on order and the work will be undertaken shortly. We will advise further when we have a confirmed date & time.
There should be no impact on the rack up-time as the main data-centre UPS will be on-line at all times, but as this rack contains a number of our core switches and there’s always the possibility of an unforseen problem, we consider that this should be noted as “at risk” work.
