Maintenances and incidents regarding our services, networks and datacenters can be followed here.
A scheduled maintenance is planned in DC5 in order to upgrade our optical transmission infrastructure.
The nature of this work is to perform a software upgrade just on one of our DWDM equipment units.
Impact: no production downtime during the maintenance window.
Updates will be posted below as the maintenance is going on.
Start : December 03st, 2020 - 08:00 UTC
Duration : 2 hours
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
A scheduled maintenance is planned in DC5 (Room 1 - B5, B9, B10, B11) in order to optimize and upgrade our infrastructure.
It will be done gradually on the racks, in the same order as in the object of the maintenance.
As a result servers will lose their public network connectivity as our switches are being upgraded, but private network connectivity will still be functional. It will come back gradually following the scheduled upgrades. We estimate the downtime to be between 20 and 30 minutes.
Updates will be posted below as the maintenance is going on.
Start : December 09th, 2020 - 06:00 UTC
Duration : 2 hours
