As several people here have pointed out, Iran is not disconnected from the Internet. Users in Iran have been able to connect to the internet without any atypical problem... this rumor has been swirling about for a few days. I manage a Persian-language website with many readers in Iran, so I have both the motivation and the resources to check into this... we've seen no decrease in traffic from within Iran. I've also been able to find no source for this that doesn't trace back to the Internet Traffic Report, which as other has pointed out has a somewhat inexact methodology. This is the second time this has been mentioned in Slashdot, and everytime it is posted, it gives me a heart-attack... there might be a need to post a correction or at the very least to stop asserting that Iran has no connectivity without better confirmation.
