[PAR Scaleway] Load balancer maintenance, scheduled 9 months ago

Maintenance Window: 2024-03-07T13:00:00Z - 2024-03-07T17:00:00Z (UTC)

Scope:

  • Database Load Balancer (software and hardware upgrade)
  • Application Load Balancer (software and hardware upgrade)

Expected Impact:

  • Brief disconnections or connection drops during the upgrade process.
  • Potential minor performance fluctuations.

Additional Information:

  • Software upgrade already record on cleverapps.io (https://www.clevercloudstatus.com/incident/803) and on Paris load balancers (https://www.clevercloudstatus.com/incident/807 and https://www.clevercloudstatus.com/incident/805)
  • Please report any issues with a method for reproducing the problem (e.g., curl command for application load balancer issues and/or psql / redis / mysql queries for database load balancer).

EDIT : We will do the maintenance next week on 2024-03-07.

EDIT 17:30 UTC : We have finished to deploy the load balancers alongside the current ones. We will switch the traffic from the old one to the new one.

EDIT 17:32 UTC : We have switch the traffic from old to new database load balancer with a unexpected behavior which is fixed now. We may have seen unexpected connections refused.

EDIT 17:35 UTC : We will begin to switch the application load balancer soon.

EDIT 17:50 UTC : We have switched the first instance of application load balancer.

EDIT 18:00 UTC : We have finished to roll the application load balancer. We are watching.
