I do use the JS api's and it was affecting my website. I was seeing a high number of JS errors and even worse, my users were seeing odd behavior because I was depending on your /track callbacks to fire and they weren't.

This is the second time you guys have had a major outage in recent memory and your status page looks like a christmas tree. I really do love mixpanel, but unfortunately I'm going to relegate your service in my mind to 'untrustworthy third party service' every time I write code against your api.

Also the fact that I found a pretty major bug in your loader code which prevents it from working correctly with IE browsers (https://mixpanel.com/docs/integration-libraries/javascript) last week and today you are still distributing the broken code has me worried. Do you not take this stuff seriously?
