All,
The Beta Cluster[0] is currently not being updated with new code[1]. That normally happens every ~10 minutes.
The issue is that we were not prepared for the php5.3 -> 5.5 transition; the deployment bastion that runs the code update ('scap') is a Precise image. We (Tyler) are currently working on rebuilding it with a Trusty image to solve this problem.
I know how frustrating this is for everyone (believe me) and I apologize on behalf of Release Engineering for the second fallout of the php5.3 -> 5.5 transition (the first being yesterday's CI resource exhaustion).
I will update the list when Beta Cluster is back to normal.
Greg
