Let's say I need to change the CNAME for my subdomain
I want it to go to a load balancer endpoint
But in creating the CNAME, I type it wrong. e.g.
Since it's possible that a client can cache DNS for up to 48hrs (despite what the TTL setting is), could this cause
test.mysite.example to be down for 48hours? Even though I immediately fix the CNAME after noticing the typo?
