Just as thousands took to Twitter to comment on the presidential motorcade as it made its way through Washington, D.C. after the second inauguration for Barack Obama, bam: Twitter's website appears to have stopped working.
Twitter.com became inaccessible from two browsers, Google Chrome and Firefox, for HuffPost staffers starting around 4 p.m. ET. However, Twitter's iOS apps for iPhones and iPads seem to be working fine -- if you really need to scratch that Twitter itch.
The website downrightnow also reported the outage, writing that it is having "Likely Service Disruption." A similar site, "Down For Everyone Or Just Me," also noted that "It's not just you! http://twitter.com looks down from here."
We've reached out to Twitter and will update with comment when we receive it.
UPDATE 1: Just before 5 p.m. ET, the company confirmed the issue on its status blog. "Some users may be experiencing issues accessing Twitter," it reads. "Our engineers are currently working to resolve the issue."
UPDATE 2: At about midnight, Twitter updated its blog: "This incident has been resolved." But not before users complained about how long it took the engineering team to get the website up and running at full capacity again.
