Status: Investigating Development instances are currently down. We are investigating. We do not expect this to extend to production instances.

Status: Investigating We're continuing investigating the issue, and will post more updates soon

Status: Investigating We are investigating an issue with DNS resolution for development hosts on our accounts.dev "accounts.dev": http://accounts.dev domain. Production instances are unaffected

Status: Investigating We have made a configuration change and are monitoring for signs of recovery. Continuing to investigate the root cause.

Status: Investigating We're continuing to investigate the root cause. Working with our DNS provider to resolve the issue

Status: Investigating We are experiencing elevated latency. The issue has been identified and a fix is being implemented Affected components Go live (Degraded performance) Analytics (Degraded performance) SMS delivery (Degraded performance) User and authentication (Degraded performance) Billing (Degraded performance) Dashboard (Degraded performance) Session management (Degraded performance) Search (Degraded performance) Machine authentication (Degraded performance) Webhooks (Degraded performance) B2B SaaS (Degraded performance) Email delivery (Degraded performance)

Status: Investigating Our DNS provider is is having an outage, which has caused most of our major services not to resolve. We're currently investigating actively.

Status: Investigating Clerk services are unable to be resolved via DNS due to a provider outage, cached DNS may be keeping things up temporarily Affected components User and authentication (Partial outage) Billing (Partial outage) Machine authentication (Partial outage) Webhooks (Partial outage) B2B SaaS (Partial outage) Email delivery (Full outage) SMS delivery (Full outage)

Status: Investigating In order to mitigate this issue temporarily, we recommend updating your DNS settings as such: CNAME `accounts.` -> `worker.clerkprod-cloudflare.net` CNAME `clerk.` -> `worker.clerkprod-cloudflare.net` Affected components Webhooks (Partial outage) B2B SaaS (Partial outage) Email delivery (Full outage) SMS delivery (Full outage) User and authentication (Partial outage) Billing (Partial outage) Machine authentication (Partial outage)

Status: Investigating For fastest manual recovery, we still recommend updating your own DNS records manually: CNAME `accounts.` -> `worker.clerkprod-cloudflare.net` CNAME `clerk.` -> `worker.clerkprod-cloudflare.net` We also have updated our nameservers to resolve to a fallback DNS provider, though we are observing that propagation is still underway. Once resolution occurs through either approach, most of Clerk's service will recover, but email-based authentication will still encounter validation issues. We are in the process of updating our fallback DNS provider with the appropriate email records. Affected components Machine authentication (Partial outage) Webhooks (Partial outage) B2B SaaS (Partial outage) Email delivery (Full outage) SMS delivery (Full outage) User and authentication (Partial outage) Billing (Partial outage)

Status: Investigating We have restored DNS resolution for `accounts.clerk.services` and `frontend-api.clerk.services` - no need to update DNS records anymore. If you previously updated your DNS records, you can change them back (but if you leave them as they are, it will be fine, nothing will go down). Email/SMS services continue to be impacted by the DNS provider outage.

Status: Investigating Our metrics have indicated that for a small percentage of customers, Apple mail services (any email with @icloud.com or @me.com) are consistently blocking emails sent from Clerk or marking them as spam. We have not seen any pattern around why this happens to some customers and not others, and have no information around why Apple is blocking emails. This appears to apply only to Apple email addresses, not email addresses from any other provider. We are actively investigating and trying to get more information from Apple around how this can be resolved. Affected components Email delivery (Degraded performance)
