Information is limited regarding outages for users on both Twitter (TWTR  ) and Meta's (META  ) Instagram on Thursday, June 14. At the peak of the outages, as many as 50,000 Twitter users were unable to access the site, and 24,000 Instagram users were unable to access that platform, according to outage-tracking site Downdetector.

The Twitter outage lasted for three hours, with the peak hitting at around 8:15 a.m., ET, on Thursday. By 9 a.m., there were roughly 2,000 users still affected.

"Some of you are having issues accessing Twitter and we're working to get it back up and running for everyone. Thanks for sticking with us," Twitter posted on its site.

According to Twitter's status dashboard, the incident was resolved by just after 6 p.m., ET. The company hasn't provided any detailed information about what may have caused the outage.

"We had some trouble with our internal systems that impacted many of you globally. Twitter should be up and running as expected," the company tweeted.

So far, analysts with Wells Fargo Securities (WFC  ) have confirmed that the Twitter outage wasn't caused by a problem with the site's cloud infrastructure. The social media site is hosted on Amazon Web Services (AMZN  ), with Google Cloud (GOOGL  ) as a secondary vendor.

"It doesn't seem to be a problem with its cloud vendors as other services continue to run," Wells Fargo analyst Brian Fitzgerald said.

Instagram's outage peaked at around 5 p.m. on the same day, but it's somewhat unclear how long the outage lasted. Reuters reported around an hour after the outage began that 2,000 users were still locked out.

"We're aware that some people are having trouble accessing Instagram. We're working to get things back to normal and apologize for any inconvenience," Meta said in a statement.

Outages on these major social media sites are relatively common. Early in its lifespan, Twitter was even known for its frequent outages. In February, the site saw another widespread outage and reported that the incident was caused by a software glitch.

Last October, Meta's platforms were down for more than six hours, the largest outage Downdetector had ever reported, with more than 10.6 million problems reported around the globe while the sites were down.
