Hey All - I am pretty new to Cloudflare and I am working to make some changes to my companies config. I updated the name servers from some older cloudflare name servers (blair.ns.cloudflare.com & cesar.ns.cloudflare.com) to newer ones per the banner and now my site is unreachable and giving me Cloudflare 1000 errors. Why would this happen?

If you changed the nameservers then it means you were not in the account where your domain was managed before. You have now changed your domain's nameservers to use the Cloudflare account you are now logged into, and I guess you have imported the DNS records which means you've probably brought in Cloudflare proxy IPs instead of your origin IPs.
Probably easiest to start with what is the domain, and can you log into the account that was managing it before where the nameservers are blair and cesar?
(It's very common for people and companies to lose track of who set up and managed the Cloudflare account and add their domain to a new account instead).

If you don't have access to the other account, then you'll need to use the new one and stay with the nameservers you have updated at your registrar. If the A records in your Cloudflare DNS start 104.21.x.x 172.67.x.x (and there's a pair of matching AAAA records too) then you have just imported the proxied records from the domain into your DNS. You will need to check who your web host is and set the correct records to point to them.

Suggest to your team that at least 2 members of staff have access to the new Cloudflare account, plus a break glass account for emergency use.
