2017-09-27 00:05 UTC: During the release process, one of our internal components was briefly overloaded, which affected primarily user sessions on our platform (https://app.thousandeyes.com) and API access to some extent. 

2017-09-27 00:15 UTC: Our engineering team found the root cause and the fix has been pushed.

2017-09-27 00:50 UTC: At this point of time, all services have been restored. We also confirmed that API should have remained unaffected throughout this problem.
