UPDATE: 1:01 a.m. EDT — Twitter is back after a brief outage. The microblogging website went down about 10:40 p.m. EDT Wednesday and returned to normalcy post-midnight.

UPDATE: 12:17 a.m. EDT — Twitter outage is likely intermittent as users in the U.S. and Australia have complained of the service going up for a while and then becoming inaccessible after refreshing.

Some Twitter users are also complaining that the microblogging website is partially up with the notifications section not opening. Twitter said the outage is a “partial service disruption.”

“Some users may be experiencing problems reaching twitter.com and using the twitter mobile apps. We're working on a fix,” Twitter said. Meanwhile, people have taken to Facebook to discuss about the Twitter outage.

Original story:

Twitter is currently inaccessible across the United States, Japan and Australia. However, third party services, including Tweetdeck, are still working with limited functionality, according to Business Insider.

An error message shows up when users go to the Twitter website, while the mobile app hangs after refreshing the feed. The issue seems to have started 10:50 p.m. EDT Thursday. 

However, Periscope and Vine services are working fine.

In January, users in Europe, U.S. and Japan complained that Twitter was down with a message: “Something went technically wrong. Thanks for noticing — we're going to fix it up and have things back to normal soon.”
