Resolved
Service by our old Load Balancer has been restored and all sites should be working whether or not you have updated your DNS as recommended in earlier updates. If you still have any trouble, please follow up in the helpdesk if you have a Pro+ plan, or in https://answers.netlify.com/t/followups-from-25-mar-2021-service-degradation/34913 if you do not.

We will post a root cause analysis about this incident and how we'll prevent recurrence going forward on our blog, and link it from this status page incident as well.

Update
Our upstream provider is working to resolve the issue which is impacting bare domains which use the now-old 104.198.14.52 IP. The provider advises us the estimated time to fix is still several hours, so we advise you to update the A record value for your site(s) bare domain to 75.2.60.5, in order to mitigate against this outage. This link – https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-an-apex-domain – contains instructions to perform this action.

Update
Our team have created a new load balancer instance which is not associated with the upstream provider who is currently experiencing issues. Please update A record values for your site(s) bare domain to 75.2.60.5 to mitigate against this outage. This link – https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-an-apex-domain – contains instructions to perform this action.

Identified
We have identified the issue and it is attributed to an upstream provider. We will continue to provide updates as we receive them.
For clarification, only sites which use our special load balancer IP as an A record value with their DNS not hosted on Netlify are affected (learn more about this config at https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/#configure-an-apex-domain).

Investigating
We are currently experiencing issues in serving traffic via our CDN where the apex domain is the primary domain in the Netlify UI and Netlify DNS is not used.
