Dear Customer ,
We have scheduled a maintenance window to remediate a critical electrical power issue in the Carlow Data Centre for Friday 30th October from 11:00 PM to 3:00 AM Saturday morning. The work requires a complete shutdown of electrical power to the Data centre for safety reasons because the electrical engineers will be replacing the Main Circuit Breakers on both the A-side and B-side feeds and power needs to be fully isolated.
It is essential that we restore full confidence in the power feeds to the data centre as soon as possible and to ensure we do not have a reoccurrence of the A-side breaker tripping unexpectedly. We have commissioned 2 new custom designed ABB circuit breakers to replace the existing breakers and these will be fitted as soon as power is isolated. The electrical engineers have estimated 2 hours to carry out the works, however we will need to shut down all servers and network equipment in advance of the power down and it will take some time to reboot everything and verify services are fully operational. There will be a team of electrical and Systems Engineers onsite to ensure the work is carried out as quickly as possible, but we are allowing a window of 4 hours for contingency.
We will be shutting down the VMs starting at 11:00 PM, then the Cloud platform to ensure there is no impact on storage or corruption of data on your VM. We will restart the servers once power has been restored and stabilised.
We apologise for the disruption these works will cause.
