Decentralized microblogging social media platform Bluesky was hit by a partial outage due to a fiber cut.

The site experienced other unfortunate glitches, which hampered its highest day of traffic ever, but were not caused by the traffic spike.

A fiber cut on a Cogent Communications cable impacted “some customers transiting our Raleigh/Durham <> Richmond, VA backbone network," the Internet service provider said.

On the same day, Bluesky's Daniel Holms said that the company experienced "networking issues from our bare metal provider [and] Cloudflare DNS issues."

He added: "None of these have to do with the increased usage (except maybe we tripped a limit with Cloudflare?) just bad luck 🫠."

The platform, which shares many of the same core features as X (formerly Twitter) has seen a surge in users since the election of Donald Trump.

After Elon Musk bought Twitter, renamed it X, and enacted widespread changes that increased the number of bots, made Musk's tweets prominent in users' feeds, and increased the spread of right-wing content, users have threatened to leave the platform.

Bluesky, Mastodon, and Meta-owned Threads have pitched themselves as alternatives.

Trump's Musk-backed victory only increased the exodus, with Bluesky gaining more than 2.5 million new users in the past week, bringing it to 16m. One million of those came in the past day.

X is believed to have around 317m users, including bots, and saw traffic decline in the past year. But analytics firm SimilarWeb said that traffic surged the day after the election to a YTD high of 46.5 million visits in the US.
