Hello,
Along with 20% of all web-based businesses, Cal.com uses Cloudflare to help run its website, apps, and APIs.
Between roughly 6:30 a.m. and 9:45 a.m. ET Nov. 18, Cloudflare's services were down, resulting in a 3-hour period when the cal.com website, app, and API's were not consistently available.
As of 10 a.m. ET, when Cloudflare resumed its service, Cal.com and its API were fully functional.
None of your data or bookings were lost during this time period.
Please reach out to our support channel - support@cal.com - if you have any questions or ongoing concerns.
