Impacted services : Power supply of IT chains A and B

We will do the curative maintenance of certain inverters of electrical chains A and B to replace the batteries end of life.
The inverters of these electrical chains supply racks of IT halls.

Operations will be performed by our maintainer under our permanent supervision.

UPS impacted :
ASI A1 - 160 batteries - 12/04/2021
ASI A3 - 160 batteries - 14/04/2021
ASI B3 - 160 batteries - 15/04/2021

This maintenance requires isolating each UPS in order to intervene on the device.
The downtime of an UPS is estimated to take 7 hours.

The operation will be done on one UPS per day and will have no impact on your equipments housed in our Datacenter :
the others UPS of the electrical chain are sized to recover the load from the offline UPS.

A scheduled maintenance is planned in PAR1 and as a result the API will be unavailable for 30 minutes.

Actions such as instance creation, reboot, deletion and block storage management will not be possible during the maintenance window through our web console, CLI and API :


Start : April 13th, 2021 - 07.00 AM UTC - 09.00 AM CEST

Duration : 30 minutes
Posted on Apr 6, 16:01 CEST

A scheduled maintenance is planned in PAR1 and as a result the attaching and detaching of block storage to your instances may be disturbed during this window.

Actions on block storage management may not go through during the maintenance window. In such case we invite you to retry your actions a few minutes later. It will eventually go through over the patching we are applying.

Start : April 13th, 2021 - 07.30 AM UTC - 09.30 AM CEST

Duration : 4 hours and 30 minutes

A scheduled maintenance is planned in part of the room 4-3, DC3, in order to optimize and upgrade our infrastructure.
The impacted racks are : C1 → C22, D1 → D22, E1 → E21, F1 → F21

As a result servers will lose their public network connectivity as our router is being upgraded, but private network connectivity will still be functional.
Public network will be back online once the maintenance is completed.

If your server is in the said racks, you will receive a ticket on your account.

Start : 14th april, 2021 - 04.00 UTC (06.00 CEST)
Duration : 90 minutes

The following services will be unavailable during the maintenance :

- Invoice download
- Consumption dashboard
- Billing alert

We’re going to realize the preventive mechanical maintenance of generators.

The maintenance will be performed electrical chain by electrical chain, so that super-rescue generators (chain F1) can recover the load, in the event of an electrical incident coming from the usual network of energy supply.

Maintenance will be carried out according to the following forecast schedule:
• Chain A : GRA1, 10/05 and GRA2, 11/05 + load tests of generators chain A, 11/05
• Chain B : GRB1, 12/05 and GRB2, 17/05 + load tests of generators chain B, 17/05
• Chain C : GRC1, 18/05 and GRC2, 19/05 + load tests of generators chain C, 19/05
• Chain D : GRD1, 20/05 and GRD2, 25/05 + load tests of generators chain D, 25/05
• Chain F1 : GRF1-1, 26/05 and GRF1-2, 27/05+ load tests of generators chain F1, 27/05
• Chain F2 : GRF2-1, 31/05 and GRF2-2, 01/06 + load tests of generators chain F2, 01/06

Every evening, generators on which maintenance has been done will be put back into service and a generators off-load test will be performed. Load tests of at least 30 minutes will be performed after each completed chain.

No generator will remain out of service in absence of the maintenance company.

We will realized a pressurization maintenance on substation SSA, SSB and SSC.

-Sub station A, 10/05
-Sub station B, 11/05
-Sub station C, 12/05

This maintenance will be carried by our maintainer under our permanent supervision.

No impact for customer is planned.

We’re going to realize the preventive maintenance of air handling units of all site.
Maximum cut-off time per CTA : 60 min

Monday24/05 - Room 01 & 02 & 03
Thusday 25/05 - Room 04 & TGBT A
Wednesday 26/05 - TGBT B & C
Thursday 27/05 - TGBT D & F1 & F2

As a result, we will experience a loss of redundancy during the preventive maintenance of a TGBT air handling units.
No impact on TGBT cooling.

Starting CRAC backup of the local TGBT before each intervention on the concerned air handling units.
Interventions controlled by the maintainer with the possibility to restart the air handling unit very quickly.

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 : 21/06/2021to25/06/2021
• Operators halls : 21/06/2021 and23/06/2021
• IT halls n°4 : 17/06/2021 and18/06/2021
• IT halls n°3 : 16/06/2021 and17/06/2021
• IT halls n°2 : 14/06/2021 and15/06/2021
• IT halls n°1 : 14/06/2021 and15/06/2021

The maximum cut-off time per CRAC unit is otherwise defined at 1 hour.

As a result, we will experience a loss of cooling redundancy during the preventive maintenance operation of a CRAC unit (max 1h).
No impact on the cooling of facilities.
