CC-IN2P3 scheduled outages

In order to allow a better planning to our end users a yearly calendar of the IN2P3 Computing Centre’s major maintenance dates is provided. At those dates it is very probable that most or even all services of the Centre are unavailable.

The increasing complexity of the systems managed makes an accurate coordination of their downtimes necessary. Setting up a long term planning serves to achieve this goal.

Each of these downtimes can potentially impact all of our services.

For each of them a detailed list of services impacted and the scheduled planning of the work to be done will be published 10 days before . Exceptionally, it may happen that the maintenance scheduled at a date announced here does not lead to any visible outage at all.

The dates of planned downtimes one year ahead are available in the following format:

Outlook : webcals://

In addition to the dates published here there may be other partial (or full) service downtimes resulting from unexpected events, from operational constraints or as a consequence of computing security issues where the delays of intervention are incompatible with the planning presented here.

The traditional ways of news broadcast (web site, email lists, grid downtime declarations …) will continue to be used.

Please find below an archive of the operations during the CC-IN2P3 scheduled outages.
