Having some Twitter trouble? You're not alone.
Around 4:10 p.m. ET the microblogging site began experiencing spots of downtime and service issues for some users. Updates have been inaccessible from browsers Google Chrome and Firefox as well as iOS apps such as Tweetbot for iPad or iPhone. Problems included
"Down Right Now" noted a "likely service disruption" as of 4:19 p.m. ET. Similar website "Is It Down Right Now?" had noted the site was running normally as of 4:24 p.m. ET, though the comments section for their page on Twitter had some complaining of outages on Hootsuite and downtime. As these comments began streaming in, "Is It Down Right Now?" upgraded the sites status to "Possible Service Disruption."
UPDATE: Twitter appears to be back up and running normally, though the last update on Twitter's status blog still says "our engineers are currently working to resolve the issue."
UPDATE 2: Around 5:20 p.m. ET, Twitter's status blog wrote that the issue has been resolved. They also gave an explanation for the downtime:
Due to an error in a routine change, Twitter was not available from 1:08pm PDT to 1:33pm PDT. We rolled back the erroneous change as soon as we identified the issue. Additionally, some users may have experienced Tweet delivery delay from 1:33pm PDT and 1:53pm PDT. We apologize for the inconvenience.
