Brief interruptions to service expected Tue 13th Oct
6 October 2009
|
ULCC have been advised by the London Metropolitan Network that they shall be performing maintenance on their network links on Tuesday 13th October between 07:00 and 09:00 BST that is likely to cause several brief network interruptions. This may result in NDAD becoming unavailable for several periods of a couple of minutes each.

System maintenance on 24th Sept
10 September 2009
|
Due to ULCC moving offices, we need to move the NDAD database cluster management software to a different server. Theoretically this can be done without causing any disruption to the service, but as this is the first time we have performed this operation and it’s a complicated procedure, as a precaution we are advising that downtime is possible.
The move will take place on Thursday 24th September between 07:00 and 09:00 BST. Interruptions to service, if they happen, may occur at any time during the session, but should last for no more than five minutes.

Brief downtime expected Tue 8th Sep
4 September 2009
|
A problem has arisen with part of the network infrastructure hardware used by NDAD. Because this could potentially affect the resilience of the service (if other hardware issues arose at the same time), ULCC has scheduled an expedited maintenance session to fix this problem. This will take place next Tuesday 8th September between 07:00 and 08:00 BST. Access to NDAD will be interrupted during this period while the hardware is restarted, but this should take no more than 5 minutes.
