Twitter has suffered from another attack following one that left the site down for several hours last week.
Tuesday's outage was brief. The online messaging site said in its status blog Tuesday afternoon that it is analyzing its traffic data to determine the nature of the latest attack. No other details were given.
Last Thursday, Twitter was inaccessible for several hours following hacker attacks targeted at a blogger who uses the site. Fake traffic flooded Twitter, making it inaccessible for millions of legitimate users. While the blogger's accounts on Facebook and LiveJournal were also hit, only Twitter suffered an extended shutdown.
