As part of Tulip’s policy for maintenance events, we plan to post announcements in advance to Community.

What work is being performed?

The following regions/gardens will undergo the following work:

cn-* Local DNS configuration change Low - No observable impact to service availability 08-Mar-2025 10:00 PM SGT → 09-Mar-2025 2:00 AM SGT
cn-21* Kubernetes Node replacement Medium - Brief loss of service (<10 minutes) or significant performance degradation (<30 minutes) 08-Mar-2025 10:00 PM SGT → 09-Mar-2025 2:00 AM SGT
eu-3* Kube2iam version upgrade Low - No observable impact to service availability 15-Mar-2025 10:00 PM CET → 16-Mar-2025 2:00 AM CET
us-14* Local DNS configuration change Low - No observable impact to service availability 22-Mar-2025 10:00 PM EST → 23-Mar-2024 02:00 AM EST
us-15* Kube2iam version upgrade Low - No observable impact to service availability 22-Mar-2025 10:00 PM EST → 23-Mar-2024 02:00 AM EST
us-15* Database filesystem maintenance Medium - Brief loss of service (<10 minutes) or significant performance degradation (<30 minutes) 22-Mar-2025 10:00 PM EST → 23-Mar-2024 02:00 AM EST
us-11*, us-28* ARM-based server rollout Medium - Brief loss of service (<10 minutes) or significant performance degradation (<30 minutes) 22-Mar-2025 10:00 PM EST → 23-Mar-2024 02:00 AM EST

Regarding March maintenance activities:

  • Local DNS configuration change is to improve DNS reliability of Tulip services
  • Database security patch is a minor version update for security purposes that does not impact customer data but requires a short downtime window to deploy.
  • Kubernetes node replacement is related to a hardware deprecation notification from our cloud provider. Replacing affected servers requires a short downtime of individual Tulip services.
  • Kube2iam, an infrastructure tool used within AWS environments, is scheduled for a version upgrade.
  • Kubernetes nodes will be replaced with servers based on ARM processors. The node replacements will not impact Tulip customer instances but will require a short downtime to roll out.
  • Database filesystem maintenance is a recommendation from our cloud provider that involves swapping the database server disk with a replacement disk. Both old and new disks will contain the same data, but there will be a configuration change regarding the filesystem.

Please refer to our Maintenance Event Schedule for further information regarding the date and times for regional maintenance windows.
