We have been notified by London Data eXchange that they will be carrying out further work to increase the UPS capacity at the LDeX2 facility between 09:00 and 17:00 on 16/03/2020 to 18/03/2020.
This work will involve a period where each of the UPS systems needs to placed into bypass whilst the new modules are brought into service and as such the LDeX2 facility will be operating as a level of reduced redundancy for some periods whilst this work is being carried out. As such, all services hosted in LDeX2 should be considered "at-risk" for the duration of this work.
Whilst in bypass, any equipment connected to the feed supplied by that UPS unit will be running on generator power and as such should be considered at-risk in case there is an issue with the generators. Utility mains power will remain available throughout the maintenance work as a backup if required.
This maintenance work will be carried out on both the A-side and B-side UPS systems separately. At no point will both systems be under maintenance simultaneously.
All devices with dual power supplies should be connected to both the A-side and B-side PDUs, so in event of any problems on one of the feeds will still have the other feed available. All devices with single power supplies should be fed from our in-rack ATS units, which can switch between the two feeds fast enough that connected devices do not see any loss of power.
If you have any questions or if you wish to double check how your devices are connected, please don't hesitate to get in touch with our helpdesk in the usual manner.

- Affecting System - AS41000 network
We have been notified by our backhaul connectivity provider that there will be scheduled maintenance work being carrying out on their equipment in LDeX1, LDeX2 and THN between 22:00 on 28/02/2020 and 04:00 on 01/07/2018 during which time they will be reconfiguring BGP on six switches as part of work to remove legacy infrastructure from their core network.
Our network is designed to withstand the loss of one circuit and continue to function as normal, so this maintenance work should not be service affecting.
Whilst we do not anticipate a complete loss of connectivity to any part of our network during this maintenance window, there may however be a brief period of increased latency or packet loss at the start and end of the maintenance work whilst the network reconverges. As with all network maintenance of this nature, the network should be considered at risk for the disruption of the maintenance window.
If you have any questions or concerns about this maintenance work, please don't hesitate to get in touch with our helpdesk in the usual manner.
