On Sunday, September 27th, at 5 PM Pacific time, GitHub will transition to Rackspace, aiming to minimize website and push unavailability to under an hour if all goes as planned. During this process, clone, fetch, and pull operations will remain functional, and once the data synchronization and final inspection are complete, DNS entries will be switched to enable users to access the updated GitHub platform. Although user impact is expected to be minimal, an SSH client warning may occur during the first operation to the new IP, but no configuration changes will be necessary. GitHub Pages CNAME users will need to update their DNS entries to reflect the new IP address, 207.97.227.245, while sub-domains using CNAME records will automatically update. The company will provide updates via its blog and Twitter account, and users are encouraged to contact support with any questions. The transition promises benefits from the new hardware and architecture, with an appreciation for user patience during this process.
