Number of sub domains

Hey Guys,

Can anyone confirm that you can have as many custom domains as you like with Netlify? We’re looking to move an app from S3 as they’ve just changed the rules regarding how many custom domains can point to one bucket so we can’t use them anymore.

Great question @chrisdjbell , and the answer is that we can only support up to about 50 names on a single site.

But of course you can deploy multiple copies with a different list of names on each, so effectively we can host any number of hostnames for the same codebase.

This will work best if you provide an SSL certificate, or if we manage your DNS for a domain and all hostnames for a site match the pattern since we can issue one wildcard SSL certificate to cover all the names.

But up to about 50 random names will work ok too even if we handle the SSL provisioning. SSL provisioning will take QUITE awhile for sites set up with >20 names, and unless we help you with it, you’d be limited to <= 20 hostnames PER WEEK added to any single site (our SSL provider has strict rate limits and adding names one by one will hit them around 20 total names).

Best practice here would probably be to provide your own SSL certificate to start with, to ensure a smooth transition, and then we could help you migrate to a managed one once DNS is all correctly pointing to us.

Do you have anywhere you would recommend to get the cert from?

All the vendors that will sell you a certificate are pretty much equivalent, unless you need something special. I usually find the cheapest price for a wildcard certificate by googling “cheap wildcard certificate” - it always points to the same few vendors like alphassl and comodo, but there is usually someone with a “sale” on that I can only find by googling. Doing so right now I see a $42 price point that is pretty appealing :slight_smile:
