Due to faulty certificate renewal mechanism of our CDN provider, our public best-effort IPFS gateway certificate has not been renewed, which could have led to issues if the certificate validity was checked strictly. We're investigating the root cause with the CDN provider and are sorry for any inconvenience this may have caused. The issue has been resolved and monitoring has been improved to mitigate any future similar issues. The non-public IPFS backends and gateways have not been impacted in any way.
