Twitter users experienced a spotty site outage this morning with inconsistent site access. The service went down and up multiple times in a three-hour period beginning around 9 a.m. PT.

"Today's outage is due to a cascaded bug in one of our infrastructure components," the company's communications folks tweeted at 12:17 p.m. PT. "We'll provide updated information soon."

Twitter said the company is working on it. At 11:37 a.m. the site was back up. As of 11:55 a.m., it was down again. As of 12:36 p.m., the site was online again.

"Update: The issue is ongoing and engineers are working to resolve it," the status read at 10:57 a.m. PT.

Around 10:30 a.m. PT, the company posted an update to its status blog indicating that users could tweet freely. "Update: The issue has been resolved and all services are currently operational," the status read.

Twitter appeared to be completely down starting 9 a.m. PT, according to monitoring site Down Right Now, but some users were not able to access it as of 10 a.m. PT though not consistently.

"Users may be experiencing issues accessing Twitter. Our engineers are currently working to resolve the issue," the Twitter's status blog posted early this morning.

According to the stats on Pingdom, this looks to be Twitter's worst crash in months. We'll update as we get more information.
