The Behind/Ahead count in Branches page does not show any data for some repositories

*This is currently being tracked at https://jira.atlassian.com/browse/BCLOUD-17417*

Summary

Going to the Branches page in a Bitbucket repository, the Behind and Ahead columns do not show the respective number of commits. This was first reported after the Bitbucket website outage on Oct 21, 11:04 UTC.

This affects only some repositories, not all of them. We are still investigating the reason why this is affecting some repositories and not others.

Example of a repository that is affected:

https://bitbucket.org/atlassian/confluence-jira-plugin/branches/

Example of a repository that is not affected:

https://bitbucket.org/atlassian/atlassian-rest/branches/

Expected Results

The Behind and Ahead columns should show the number of commits that a particular branch is behind and ahead of master branch.

Actual Results

Behind and Ahead fields show a dash instead. See attached screenshot.
