Update 2: The attackers have admitted that the attack was a simple DDoS and that the database was not compromised. The leaked information was apparently fake.

Dropbox has gone offline due to what some are claiming is a breach of the company’s website. The company claims that the outage was caused by an issue that arose during routine maintenance.

We are aware of an issue currently affecting the Dropbox site. We have identified the cause, which was the result of an issue that arose during routine internal maintenance, and are working to fix this as soon as possible. We apologize for any inconvenience.

Hackers have claimed credit for the attack on Twitter, saying that action is being taken in honor of the one-year anniversary of the death of Aaron Swartz. They have also claimed that unless the issue is fixed quickly, they plan to release the site’s user database to the public. Dropbox has officially denied these claims.

Update: The group responsible for the breach has released what they claim is a small part of the user database online as proof that they have compromised the site.
