U.S. internet infrastructure company Cloudflare

said on Friday it had issued a fix for an issue with its dashboard and related apps.

Shares of the company fell as much as 4.5% in premarket trading after global websites went down and Cloudflare said it was investigating.

The company issued an update minutes later saying it had “implemented a fix” and was watching for results. Cloudflare shares pared some of its losses on the news and were last seen 2% lower.

Sites including professional networking platform LinkedIn, digital currency exchange Coinbase and online publishing platform Substack were among those that appeared to be impacted by the issue.
