commits web page not showing any commits on branches with recent commits

Some time in the last 24 hours one of our repos no longer shows commits on the commits web page for branches with very recent commits. Remote repos show no problems so the issue appears to be web server related.

The repo is https://bitbucket.org/k1jt/wsjtx/src/master/ and the last commit visible seems to be https://bitbucket.org/k1jt/wsjtx/commits/7ddcb798fe4d17be7c4d07a2cc4678fe4078f755?at=wsjtx-2.0.1

Bill.
