Extremely Long Loading Time

Extremely Long Loading Time

I recently started using Zoho Creator for the forms in my high school.  Up until a week or so ago everything was working fine.  Lately however, I have found that it is taking a really long time to load the forms when I am on the school network.  I noticed that you have a connection with Facebook, and my school has a block on the facebook domain.  Could this be causing the issue?  If so, is there a way to have the forms load without connecting at all to the facebook framework?
 
Thanks,
