Update on Last Night's DNS Disruption
Domain Name System or DNS is an Internet protocol used to translate IP addresses into domain names so instead of typing in a long string of numbers we can enter urls like www.twitter.com into a browser to visit our favorite web sites. Last night, DNS settings for the Twitter web site were hijacked. From 9:46pm to 11pm PST, approximately 80% of Traffic to Twitter.com was redirected to other web sites. We tweeted, blogged, and updated our status page last night.

During the attack, we were in direct contact with our DNS provider, Dynect. We worked closely to reset our DNS as quickly as possible. The motive for this attack appears to have been focused on defacing our site, not aimed at users—we don't believe any accounts were compromised. If you're concerned that your account could have been affected in some way, feel free to contact us, accountsafe [at] twitter.com."
