We experienced an issue resulting in intermittent downtime for both My Pingdom and pingdom.com.
Note: All times referenced below are Coordinated Universal Time (UTC).
At 12:30 our Operations team started receiving alerts for several of our services reporting intermittent downtime.
Both My Pingdom and pingdom.com reported instances of downtime for some customers, each occurring at 1 minute intervals, occurring 3-5 times in total. Our Operations team found that one of our upstream providers/ISPs was experiencing issues (full information can be found at: http://www.ip-only.se/blog/2016/10/17/398769/).
Service restoration was reported at 13:11, although we continued to monitor the situation. We saw no impact for Pingdom customers after the initial incident update.
