munchkin.js timing out on page load
We have this issue where when viewing our Marketo landing pages on our company network, the munchkin.js takes about 30 seconds to load, before it fails and times out. The issue is that it causes errors with our other js elements on the page until times out (ie. forms and videos that pop-up when clicked, etc) which causes issues when trying to QA not only myself, but with anyone else internally, as waiting 30ish seconds for a page to load before clicking anything is obnoxious.

I've also spoken with our IT department as high up as our VP about this, as we have deduced it is most likely related to our web filter/scan safe tool we use, because this error does not occur when not on our network/VPN. However, Every domain and extension we could identify related to Marketo has been white listed in an attempt to resolve this.
Clearly this issue seems specific to us, but we can't be the only one whose company has some web filter/scan safe tool in place, so I was wondering if anyone has experienced anything similar or could recommend what else to look at.
