- Priority - Critical
- Affecting System - AS41000 network
We have detected a DDoS attack against one of our customers which saturated some parts of our core network. We have therefore taken the appropriate steps to mitigate this attack and restore service for affected customers.
Due to the intermittent saturation of parts of the core network, some customers may have briefly seen packets loss affecting their services. This should be completely resolved as of 21:43.
Please accept our apologies for the inconvenience caused by this attack and feel free to contact our support staff via the usual means if you are still experiencing any problems or have any questions or concerns.
Update (23:33): We have not seen any further issues and therefore believe that this is resolved, however we continue to monitor the situation closely.
Update (11th April @ 12:19): We have seen a return of DDoS traffic targeting the same customer which has saturated parts of our core network causing a brief outage. We have mitigated the attack and will continue to monitor the situation.

- Affecting System - LDeX1 UPS
We have been notified by London Data eXchange that they will be carrying out work on the UPS in the LDeX1 facility between 09:00 and 17:00 on 03/04/2019 as part of their planned preventative maintenance programme.
This work will involve a firmware update, visual inspection of the components in each of the UPS systems, functional testing and cleaning of the fans and as such the LDeX1 facility may be operating as a level of reduced redundancy whilst this work is being carried out, so all services hosted in LDeX1 should be considered "at-risk" for the duration of this work.
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. During this maintenance period, it may be necessary for either of the UPS units to be placed into bypass mode. This means that any equipment connected to the feed supplied by that UPS unit will be running on raw mains power and as such should be considered at-risk in case there is an outage on the utility mains feed. Generator backup power will remain available throughout the maintenance work if required.
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.
