Netcraft, a UK-based security service provider, indicated that more than a billion of the shortened URL’s may have suffered from the attack, and those links ended up accessed “nearly 50 billion times.”

An updated blog post by site administrators said implemented a third-party DoS protection service, but ran into issues when attempting to gain administrative control of its domain to alter its configuration, thus prolonging the service’s outage.
