What do you do if your website goes down? That’s a question that several GoDaddy customers had to answer on Sep. 10, 2012, around 10:25 am PST. Although the company had most customers’ sites back up and running by 2:43 pm, for more than five hours, many small-business owners were unable to conduct business as usual.

GoDaddy kept everyone informed via Twitter. According to the latest tweet, which was posted on the evening of Sep. 10, “Most customer hosted sites back online. We’re working out the last few kinks for our site & control centers. No customer data compromised.”

While it’s fortunate that no vital information was compromised as a result of this attack, several businesses lost revenues because they could not communicate via email, and customers could not access their websites to make purchases or perform other business tasks such as creating IT support tickets or chatting with customer service reps.

According to CNN, a hacker who calls himself AnonymousOwn3r, went on Twitter to take credit for the outage.

What may seem like a harmless prank to a hacker could have a lasting effect on businesses, especially small businesses. Is your company prepared to deal with this type of disaster?
