It's been aas the company attempts to iron out longstanding problems and to prepare its servers for continued growth. The situation has led to a series of very public service outages, including a huge one Monday that left many users unable to sign in, update their profiles, or even sign up for the service in the first place.
Twitter released a series of updates on its company blogs Wednesday night about the problems and how they tie into long-term upgrades that the company has been working on. One announcement: Twitter will open a "new, custom-built" data center near Salt Lake City, Utah, later this year.
"Twitter will have full control over network and systems configuration, with a much larger footprint in a building designed specifically around our unique power and cooling needs," the company's engineering blog noted. "Importantly, having our own data center will give us the flexibility to more quickly make adjustments as our infrastructure needs change.
As for the recent problem, Twitter said that "our users database, where we store millions of user records, got hung up running a long-running query; as a result, most of the table became locked."
Twitter's ongoing problems unfortunately coincided with the World Cup soccer tournament, a monthlong extravaganza earlier this summer that.
Wednesday night's post on the company engineering blog described the whole process as "riding a rocket."
