Maintenances and incidents regarding our services, networks and datacenters can be followed here.
We're going to perform preventative maintenance on the refrigeration units at DC3. These will be stopped 1 by 1, only the redundancy is degraded.
The maintenance will be done according to the following schedule :
Start: 04.06.2020: 0800Z (0900LT) End: 04.08.2020: 1500Z (1600LT)
Impacts on services : Loss of cooling redundancy during the preventive maintenance
[DC3] Semi-annual maintenance of distribution pumps
We will do the semi-annual maintenance of the distribution pumps.Operations will be performed by our maintainer under our permanent supervision, according to the following previsional schedule:
Tuesday 14/04 Sub-stationA
Wednesday 15/04 Sub-stationB
Thursday 16/04 Sub-stationC
Substations A and B supply the chilled water network of the computer halls.Substation C supplies the chilled water network of the operators halls and the air handing units.
Impact : None
Duration : 3 Days
[DC3] Update PLC software on F1/F2 chains and load test of generators on F1 / F2 chains
Load tests of generators on IT chains with F1 line up backup test
As part of the preventive maintenance of the Datacenter, we will proceed to a redundancy test of the Datacenter infrastructure by carrying out generator tests chronologically on the following electrical chains : A / B / C / D / F1 and F2. During the load tests on the electric chains A / B / C and D, we will proceed to F1 line up backup test.
Descripton of operations :
21/04/2020: Morning: Load test on the electric chain A with F1 line up backup test.
Afternoon: Load test on the electric chain B with F1 line up backup test.
22/04/2020: Morning:Load test on the electric chain C with F1 line up backup test.
Afternoon: Load test on the electric chain D with F1 line up backup test.
23/04/2020: As part of the mobile chillers installation, we will update PLC software on chains F1 and F2. After we will proceed to load test on the chains F1 andF2. During the F1 line up backup test, we will simulate a failure of the generators in order to validate the F1 lineup backup scenario.
Our teams and usual maintenance companies will be mobilized for the perfect workflow.
Duration : 3 Days
