We’re working on making our Dagster+ web infrastructure faster and more reliable! As part of this work, some of our web infrastructure will be migrated to use AWS CloudFront’s content delivery network. We intend to migrate on June 5, 2024.

This migration will necessitate a change to the IP address range used by some of our web infrastructure. If you’re using any VPN or firewall that has IP-based restrictions then you may be adversely impacted if you do not take action.

What will be impacted:
Anyone using a VPN or firewall that requires explicit allowlisting based on IP address (not just domain name). The following Dagster+ features and services would become inaccessible on June 5 if the new IP address range is not proactively allowed:
- Dagster+ web interface
- dagster-cloud CLI
- Dagster+ GraphQL API

What action should be taken:
The IT administrator, or someone with access to your VPN/firewall rules, will need to proactively allowlist the AWS Cloudfront IP address ranges. To do this, they should visit that page, download CloudFront’s current IP address ranges in the ip-ranges.json file and allow HTTP(S) traffic to those IP address ranges.

What will not be impacted:
- Dagster agents will continue to interact with the same IP address at <org>
- Dagster+ Serverless deployments will continue to use the same documented IP addresses.
- Our domain names ( and will remain unchanged.
