Daily: Issues with joining calls from certain ISPs/regions
Affected components: Core Call Experience
Timeline of updates
- identified
Users that are using their ISP's DNS service (specifically AT&T users in the southeast US and/or Texas) are experiencing intermittent problems accessing any .co domain, including daily.co. This may result in those users seeing an “Unable to join call” error in the browser when trying to join a call. This is being caused by failures from the DNS servers that serve the .co TLD itself. Several third-party DNS providers like Google, Cloudflare, and Quad9 are working around this in order to continue to make .co domains available. To work around this, you can encourage your users to use a third-party DNS provider, like Cloudflare or Quad9.
- identified
We are working on implementing a fallback to a .com domain so that users on ISPs that are not fixing this will not see any issues starting calls.
- resolved
CentralNIC confirmed that there was indeed an issue with the .co nameservers, and they resolved it at approximately 06:30 UTC today. Our monitoring of both their DNS servers and downstream providers confirmed this. We're continuing to work urgently on updating our infrastructure to make our services available on alternate hostnames. We'll post updates to our Networking Guide when we do: https://docs.daily.co/guides/privacy-and-security/corporate-firewalls-nats-allowed-ip-list We'll also provide a root cause analysis for this incident in the next few days.
