Blog Status Twitter says it is defending against denial of service. Site is down since Thursday morning (6/8).

The microblogging service Twitter faces serious problems on Thursday (6/8). At 10 or so, the service fell and remained so until noon. Since then, alternating moments of operation with further falls.

In the blog that shows the status of the service , Twitter says only that "is defending a denial of service".

Around noon (GMT), an update was published saying that the site had returned, but the team still Twitter on high alert against further attacks.

A denial of service, or Denial of Service (DoS), sends a large volume of traffic to a website which then becomes overloaded. While some users are still able to access it, most can not see anything but a message that the response time has exceeded the limit.

The last interruption Twitter had occurred on June 16, when the site was down for an hour for scheduled maintenance.

Twitter has become a sort of digital Procon. Whenever a service goes down - business, government, or the Internet itself, it becomes a forum for complaint in real time by the Internet.

When this happens, users often use the hashtag # fail (failure in English), as a way to facilitate the search for others who are facing the same problem.

The Twitter gem about 44 million users worldwide, more than in the population of countries such as Argentina (41 million) and almost equal to that of Colombia (45 million).
