Twitter went down for about 45 minutes Tuesday morning for "most users" on both the Web and on mobile apps, according to the company's status blog.
CNET first noticed the site down just after 11 a.m. PT. Though Twitter came back intermittently for some, it remained on the fritz until about 11:45 a.m. PT.
Update, 11:59 a.m. PT: Twitter is back up for CNET employees.
Update, 12:17 p.m. PT: Twitter updated its status blog at 12:12 p.m. PT explaining the cause and timing of the outage:
During a planned deploy in one of our core services, we experienced unexpected complications that made Twitter unavailable for many users starting at 11:01am. We rolled back the change as soon as we identified the issue and began a controlled recovery to ensure stability of other parts of the service. The site was fully recovered by 11:47am PDT. We apologize for the inconvenience.
Reviewing the status blog, this appears to be the longest outage since Twitter's 2013 initial public offering. In its IPO paperwork, Twitter acknowledged its history of outages dating back to the "fail whale" days. It has since improved its stability as its user base and tweet volume has soared.
