# v1.1 1/21/2022 update to include all services

# This script asks for the 3 subdomains, checks they exist, checks they resolve locally and remotely (using google dns for remote), 
# checks services are running, checks ports are opened. The only part that will make the script stop is if the sub domains dont exist, theres literally no point in going further if thats the case
