Twitter has experienced an explosive boom in its popularity. The microblogging site has become the go-to site for many people who want to give the world a peek into their world, whether it’s exciting or mundane.

That’s why any kind of snags in Twitter’s operations can have a big impact. Just like what happened last Thursday when Twitter was hit by a denial-of-service attack. Twitter didn’t immediately acknowedge the attack. It didn’t offer an explanation for the disruption of service and only placed an innocuous “Site is down” message. Twitter finally revealed the Ddos attack a couple of hours after it placed the “site is down” sign. The new message on the Twitter status blog was, “We are defending against a denial-of-service attack, and will update status again shortly.” Twitter reported that the site was back up at around 11:21 AM EDT but some people still reported not being able to access the site.
