The following guide outlines how to mitigate the impact of a Netlify load balancer experiencing service degradation.
Since March 2021, the correct load balancer IP is
220.127.116.11. Previous load balancer IP addresses will eventually be deprecated.
An apex record is the DNS record for the bare domain you own, e.g.
my-site.com - where
mydomain is your domain and
.co.uk is the top-level-domain.
For any records that are not apex records (such as
www.my-domain.co.uk) you should not be using an
A record. Instead, you should use a
CNAME record. See our docs for more details.
If you add a domain without a subdomain to your site, Netlify will automatically handle the
www subdomain for it and redirect to a single primary domain. Use the domain settings on your site to ensure that the
www. variant is your primary domain so it will be used for serving the actual content.
www. variant is configured with a
CNAME record and configured to be the primary domain for your site, the load balancer will not be relied upon.
If you’re using Netlify DNS for your domain, your site will never use the load balancer for the apex. Consider using Netlify DNS for our most reliable configuration! See the docs for more details.
With some DNS providers, you can use CNAME flattening to avoid using the load balancer. Those providers allow you to use a CNAME record on your apex domain. There is a guide on which providers allow this: [Support Guide] Which are some good DNS providers for ALIAS/ANAME support?
If you are not able to switch the DNS record on your apex you can give your customers the
www. variant of your domain manually to make sure they will get a DNS record that doesn’t point to the load balancer.
