[ci.jenkins.io] Maintenance with full downtime today

[Damien Duportal]

Hi dear contributors,

The Jenkins Infra team will perform a maintenance on ci.jenkins.io starting at 12:30pm (noon time) UTC today with full downtime.

The goal is to move the service to a new VM in another Azure subscription where we have credits to pay for the resources (instead of having a billing with the current VM). 

More details in https://github.com/jenkins-infra/helpdesk/issues/3913.

We expect 1 hour of downtime, but we will send an email to let you know 1 hour after the beginning (or if we finished earlier).

Update : operation still in progress. No blockers, but we are slower than expected.

Operation is finished and ci.jenkins.io is operating succesfully.
