(NEW YORK) — Web infrastructure company Cloudflare said Tueday it resolved an issue on its network, which had curtailed access to some popular websites for several hours.

“A fix has been implemented and we believe the incident is now resolved,” Cloudflare said on its status page at around 10 a.m. ET.

Hours earlier, the company issued an alert about a problem affecting “multiple customers.”

“Cloudflare is aware of, and investigating an issue which potentially impacts multiple customers,” the company said at around 7 a.m. ET.

Minutes later, the company said it had begun to resolve the issue. “We are seeing services recover, but customers may continue to observe higher-than-normal error rates as we continue remediation efforts,” Cloudflare said.

Some popular websites, like social media platform X and artificial-intelligence chatbot ChatGPT, appeared to be temporarily down or limited on Tuesday.

Cloudflare helps companies handle user traffic, including efforts to respond to cyberattacks and load information.

On Tuesday morning, a landing page on X alerted ABC News to an “internal server error,” urging users to “visit cloudflare.com for more information.” A similar warning appeared on ChatGPT’s website, telling ABC News to “please unblock challenges.cloudflare.com to proceed.”

X did not immediately respond to ABC News’ request for comment. Neither did OpenAI, the company behind ChatGPT.

ChatGPT and X appeared to be available for users as of 10:30am ET.
