New Mistake Everyday - Conjuction - As and If

Yesterday, I tweeted, "29 new universities have just participated @coursera! I might be browsing the new classes offered as the web is not down."

There are two ways to revise my sentence, namely:

1. Twenty nine new universities have just participated @coursera! I might be browsing the new classes offered if the web were not down.
2. Twenty nine new universities have just participated @coursera! I will be browsing the new classes offered as the web is not down.

Can you tell the difference?
