Following on from the power disruption back in March 2013 that affected our London Leve3 suite. We have been advised that our supplier is upgrading our suite to a Tier 4 specification
This is a welcome upgrade and means that both our A&B power feeds will be fed from independent UPS rooms and independent generator banks.
Our core network and customer facing services (EasyHTTP, EasyIPT & EasyBOND) are fully power redundant and no service disruption is expected, however they will be classed as “at risk” for the 24 hours while the work is undertaken starting at 22:00 hours on the 17th Feb until 22:00 hours on the 18th Feb.
We will be attending site for the duration and taking the B feed out of service prior to the works in a controlled manor. Any customer services with only a single fed supply currently on B will be transferred to A prior to the work and returned once complete.
UPDATE 01 – 20:30 – 17/02/2014
Engineers have been onsite all day and prep work is now underway. Traffic is going to be transfered from AG-Primary to AG-Backup, this will cause a 30 second outage while devices transfer.
UPDATE 02 – 22:00 – 17/02/2014
An unexpected outage was seen for EasyBond circuits where an old version of the NOC came online due to ESXi01 not saving it’s startup configuration on shutdown. This has resulted in some stale sessions. Please power down your hardware for 20 minutes where power routers are in PPPOE mode or STATIC IP.
