Intervals will be undergoing server maintenance this weekend. The maintenance will be performed January 17th during a two hour maintenance window of 5:00 AM - 7:00 AM (PST) | 1:00 PM - 3:00 PM (GMT). We may encounter a few minutes of down time but hopefully no more than 5-10 minutes.
The server maintenance is complete and fortunately downtime was kept to about a minute. This maintenance laid the groundwork for some upcoming optimizations.
Regarding this evening, we have seen a few oddities with our probes and monitoring services and we are currently investigating the matter to see if we can determine what is happening. Your feedback enforces what we are seeing with the probes. Thank you for your patience while we try to isolate the problem.
After investigating the matter it looks like there was a configuration problem with some of the optimizations that were launched earlier this weekend. We tuned things yesterday and have been monitoring things today and everything appears normal. If you are still seeing any sluggishness or intermittent problems please let us know.
