We also just noticed our DNS settings has been reset. We have corrected the problem, but this would have prevented alerts from being sent out. Please manually confirm your jobs, whether you got an alert or not. Please be on the lookout for both false negatives and false positives. We apologize for the inconvenience.
We just noticed the time on the server was off by a couple of hours, which shows pings are happening 10 hours in the future. This has been fixed, but will send off false alerts for some URLs. Please keep this in mind as the system corrects itself. Thanks for your patience.
We are currently having issues in our data center, and all our servers are inaccessible. Please ignore any alerts you get for pings that should happen during this downtime period. It will be prudent to manually verify your jobs as well. We are sorry for the inconvenience.
