Acquia is currently undergoing a technology refresh for the Acquia platform infrastructure for customers with applications currently operating outside the shared Acquia Virtual Private Cloud (VPC). As part of this process, we are upgrading infrastructure that has reached its end-of-life support on the Acquia platform. This effort will begin in March 2019 and continue in phases on an ongoing basis until complete.
Q: What does this effort involve?
Acquia is currently moving portions of the Acquia platform to newer infrastructure to enable additional functionality and performance improvements to customer applications. This allows Acquia to reduce platform technical debt while improving performance and security for the infrastructure supporting our customer applications.
Q: What impact will this effort have on my application?
During this maintenance window, your application will experience approximately five minutes of total downtime over the course of an eight-hour maintenance window. This maintenance window will occur during regional dark time hours (11:00pm to 7:00am local) to minimize impact to your applications.
Please Note: Your application's high-availability will be impaired as we upgrade your infrastructure. Varnish will continue to serve cached traffic during most of the update process. High volume applications with heavy reliance on Varnish and Memcache caching may experience temporary performance degradation while the cache rebuilds immediately after the update.
Additionally, staging and dev environments for applications without high availability will be unavailable for approximately 30 minutes during this maintenance.
Q: Is any action required on my part?
Customers that have an Elastic Load Balancer (ELB) in place will need to repoint their DNS to our migrate.acquia.com address prior to this maintenance. You will receive a ticket providing you with instructions for making this change, which is detailed in our documentation, "Updating Your DNS for your Technology Refresh Migration."
For customers with applications that do not have an ELB in place, no action is required.
Q: How do I know if I will be impacted by this effort?
Customers with applications that will be impacted will receive individual tickets for each of their impacted subscriptions, along with dates and times of the individual scheduled maintenance.
Q: I have additional questions. Who can I talk to?
