All IPs have been moved, and the old IPs are no longer handling traffic.
Thanks to you, Bitbucket is outgrowing its old network infrastructure. We’re going to make some upgrades that should make Bitbucket faster, more reliable, and ready for further growth.
What are we doing?
We’re changing our A records in DNS starting at 00:00 UTC on Tuesday, December 15, 2015. There will not be any downtime for this migration, and most people will not have to do anything differently because of this migration.
Why are we doing this?
Our new IP address space, along with some underlying network improvements, should make response times noticeably faster for about a third of our users. Just as important, these changes make it easier for us to improve upstream network connectivity and load balancing, and to perform other infrastructure projects in the near future.
How will this affect you?
Most users will not have to do anything special for this migration. Your DNS servers should pick up the new IPs within a few minutes of the migration, and your systems should start using the new IPs right away. We’ll keep the old IPs running for a few weeks afterwards just in case, though.
If you control inbound or outbound access with a firewall, though, then you may need to update your configuration. Please whitelist these new IPs now; you should be able to remove the old IPs after the migration is complete.
New destination IP addresses for bitbucket.org will be:
New source IP addresses for hooks will be:
Our server’s SSH key is not changing, so most SSH clients will continue to work without interruption. However, a small number of users may see a warning similar to this when they push or pull over SSH:
Warning: the RSA host key for ‘bitbucket.org’ differs from the key for the IP address ‘126.96.36.199’
The warning message will also tell you which lines in your ~/.ssh/known_hosts need to change. Open that file in your favorite editor, remove or comment out those lines, then retry your push or pull.
As we update records, we’ll post updates on our @BitbucketStatus Twitter account and our status site so you can follow along. We’ll also keep our knowledge base up-to-date with any future changes to the lists of IPs.
Thanks for your patience as we work to increase Bitbucket’s speed and reliability. Please contact us at email@example.com if you have any questions.
