Hashrate Graph Stuck

I was doing some work on my miners this morning, because one of my cubes decided to eat it's power connection. After I got everything put back together and operational again, I noticed that my hashrate graph wasn't updating. I checked back throughout the day, and while shares are being counted, and the Current Worker Status info is updating normally, the Hashrate graph is stuck at noon. Am I the only person affected by this?

This issue resolved itself. Was it related at all to yesterday's outage?

Yes, the hashrate graph doesn't update when the latest share in the database is more than five minutes old. This restriction is there to prevent the graph from calculating a hashrate of zero when shares are delayed. All the missing previous points on the graph are calculated once the database is up to date.

In the case when the mining server is offline, then the graph will never update because there will never be any shares inserted in the last five minutes. Once the server was restarted, shares resumed being recorded and the graph updated all previous points.
