Release notes

October 30, 2018

Here’s the latest on how we’ve been trying to make simpler and more secure. (If you find yourself needing to explain to coworkers or leadership, take a look at our new two-pager!)

New S3 plan for sandboxes

October 22, 2018

In the past, we’ve had issues with users being notified of a sandbox purge even though the sandbox didn’t actually get cleared. So in order to provide a more seamless experience, now offers S3 service plans for sandboxes that automatically clear your S3 contents whenever your sandbox is cleared.

New custom domain service

May 21, 2018

For custom domain support, provides a CDN service that uses AWS CloudFront. AWS CloudFront is outside the AWS FedRAMP P-ATO boundary, so we’ve updated the CDN service documentation to explain the compliance impact of using this service more clearly.

TLS 1.0 and 1.1 support removal, Drupal 8 made easy, and platform updates

March 14, 2018

Upcoming breaking change

  • We will remove support for TLS 1.0 and 1.1 connections to all applications on on March 30, so that all connections must use TLS 1.2. TLS 1.0 and 1.1 are outdated versions of the encryption protocol for HTTPS connections, and federal standards require federal systems to stop using them (see FedRAMP TLS Requirements). After this change, your applications will be inaccessible for anyone using a client device that requires TLS 1.1 or lower. We estimate this change will block less than 1 percent of traffic that reaches applications hosted on today. It’s probably required for your applications by your own agency as well, but if you have any concerns or questions, please contact us.
