I am using ANT tool for deploying code into my org and today, when I am trying to deploy the code, it is throwing following exception in about 281 classes:

An unexpected error occurred. Please include this ErrorId if you contact support: 94477506-8488 (-1165391008)

I understand that this is Salesforce internal error and we need to raise a case with Salesforce about it but does anyone have any idea what it can be?
