Its very unlikely for these reasons:
- limited lifetime
- we have already seen volcanic eruptions which put a lot of SO2 into the stratosphere, and thet did not cause an ice age, so it’s clearly fine if we don’t put too much
Anyway, that’s what research is for.
Here is how I would diagnose (I’m assuming you have Linux / WSL on a client)
dig $domain
check which server answereddig a $domain
should give a recorddig a $domain @server
to make sure you’re querying the right serverIf none work, probably network issue (DNS boind to wrong IP, firewall, etc)
If 3 and 5 work but 4 doesn’t, your DNS isn’t authorative.
If only 5 works DNS settings on the client is wrong.
