The Iranian website ahmadinejad.com, in which Iranian officials claim the Iranian President publishes a daily journal ,was down for a few hours on Monday.
Following a report by Yedioth Ahronoth on Sunday about the site, Israeli hackers called for a joint effort to hack the site.
On Monday afternoon, the site was down for an hour and in the evening the site worked alternately.
Israelis bloggers claimed Monday that the site was down because of a joint effort by thousands of Israelis to enter the site simultaneously, causing it to crash.
Despite the effort, the site was operational late Sunday evening.
