We are growing fast. Faster than we actually thought we would. We hit memory limits on 2 of our servers (WebEngage production server and Screen-capture service server) because of which no new processes could be created. The site remained unreachable this morning. Ankit and myself spent over an hour trying to restore things back to normal. And I am pleased to inform you that we are back.
The feedback tab and klipping functionalities would not have responded in the last hour or so. We apologize for the inconvenience caused to you and your site visitors. You can claim your complementary mug of beer from our office if you are a WebEngage publisher 
However, we have grown better with this experience. There will be round-the-clock monitoring via our health check scripts to detect and fix such outages quickly. Moreover, there is a massive scale up provisioned on our server infrastructure sometime soon. Once that happens, such outages will become history.
Stay tuned. We love you!
Does that mean the site’s that had your script were loading slow or not loading at all?
Well, the feedback button would have loaded for all your users without any latency. However, those who would have tried to click on the feedback tab would have found the loading of feedback window to be extremely slow.
