Finish: 09/02/2016 05:00 GMT
Task:
One of our interconnect suppliers will be upgrading their capacity with BTW for DSL services in Telehouse North. This will involve migrating traffic on a pair of interconnects to new, higher capacity ones.
Customer Impact:
We do not anticipate any impact to Merula customer traffic, however all BT DSL services delivered from our Telehouse North node should be considered as AT RISK during this maintenance window.
If you have any queries about this work please raise a support ticket with our helpdesk.
We will issue an ALL CLEAR once this work has been completed.

COMPLETED: All Work was completed during the evening on 26th November and the Data Centre now has full access to both Mains Power, Generator Power and the UPS. There was no outage to hosted servers during the work.
UPDATE: we will have engineers on site on Thursday 26th, to replace parts in our automatic transfer panel. Most of the work will not be service affecting, however there will be a short period where the data centre will be supplied by UPS alone. While we don’t anticipate any disruption, the power to our racks should be considered at risk during this period. All “at risk” work will be carried out outside core business hours and we will have staff and external electricians on site as needed to monitor/resolve any issues found.
UPDATE: the engineers are about to isolate the mains supply and generator and move us over to UPS power. This has been tested to support the data centre for at least 30 minutes but for the period of down-time, we are at risk.
We are aware of an issue with our changeover panel here and an engineer is en-route to work on this.
If the panel needs to go off-line then resilience will be reduced for a short period but the generator and UPS are still available and have just been fully tested as part of our normal weekly maintenance regime and will cut in automatically. As a reminder, the generator has fuel for at least 24-hours of continuous running.
Once the panel issue has been resolved, we’ll update this post.

[UDATE] All work completed to plan.
We plan on making some further changes to a couple of our core network routers to isolate and correct a service setting that is causing a few BGP issues.
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.
If this planning changes, we will update this ticket

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.

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.
