Maintenances and incidents regarding our services, networks and datacenters can be followed here.
Location : DC3 datacenter
What is done : As part of an annual checks, we will verify the air handling installations in the DC3 data center. This intervention take 4 days and will be supervised by our control office.
Impact : none, it is an electrical check
Duration : 4 days
Location : DC5 datacenter
What is done : As part of an annual checks, we will verify the inverters of the electric chains in the DC5 data center. This intervention take 4 days and will be supervised by our control office.
Impact : none, it is an electrical check
Duration : 4 days
Tuesday 10/11 Wednesday 12/11 morning Wednesday 12/11 afternoon Thursday 13/11
Location : DC3 datacenter
What is done : As part of an annual checks, we will verify the electrical installations on all the electrical component in the DC3 data center. This intervention take 8 days and will be supervised by our control office.
Impact : none, it is an electrical check
Duration : 1 week
Location : DC3 datacenter
What is done : As part of an annual checks, we will verify the circulation pumps installations in the DC3 data center. This intervention take 2 days and will be supervised by our control office.
Impact : none, it is an electrical check
Duration : 2 days
As part of an annual checks, we are going to carry out a thermography in the DC3 datacenter.
This intervention take 6 days and will be supervised by our control office.
Duration : 6 days
We will realized a pressurizationmaintenance on substation SSA, SSB and SSC.
This maintenance will be carried by our maintainer under our permanent supervision.
Location : DC5 datacenter
What is done : As part of an annual checks, we will verify the electrical installations on all the electrical component in the DC5 data center. This intervention take 8 days and will be supervised by our control office.
Impact : LOW Electrical Redundancy Loss
Duration : 3 days
Every evening, the generators on which maintenance are been performed will be put back into service. No group will remain out of service in the absence of the maintainer.
We will carry out the semi-annual preventive maintenance of CRAC units according to the schedule below.
CRAC units will be shut down one at a time, so as not to impact the cooling of halls.
Each IT zone has CRAC unit called «backup»: each CRAC unit is doubled.
Each MVLB hall has a main air hanling unit (AHU).
The maintenance will be done according to the following schedule:
• MLVBs: 09/12/2020 to 11/12/2020
• Operators halls: 04/12/2020
• IT halls n°4: 07/12/2020 and 10/12/2020
• IT halls n°3: 07/12/2020 and 09/12/2020
• IT halls n°2: 08/12/2020
• IT halls n°1: 08/12/2020
The maximum cut-off time per CRAC unit is otherwise defined at 1 hour.
Impact: Loss of cooling redundancy during the preventive maintenance operation of a CRAC unit (max 1h). No impact on the cooling of facilities.
Supervision of return and blowing temperatures during operation. Interventions mastered by the maintainer with the possibility of returning very quickly in initial configuration in the event of anomaly.
In the event of fault not immediately correctible and impacting the operation of the “backup” CRAC unit associated with the CRAC unit in maintenance, the maintainer will restart the CRAC unit in maintenance very quickly. If necessary, CRAC units adjacent to the faulty zone may be switched to degraded (forced) operation.
Duration: 6 business days
