I run feeds for MeTHoDx and bm.payroll.riverhead on a different VPS than the block signing wallet. The VPS was rebooted to have a software issue fixed (by them, not me) and the feeds did not come back up.
Sorry for the down time. They are back up now.
Last feed before down time: December 8, 2014 at 11:04:10 PM EST
Latest publish: December 10, 2014 at 11:58:00 AM EST
Total feed down time: 1 day, 13 hours.
And yes, if I happen to not notice something like this again please DO pester me.
