I cringe every time this happens.
Takes forever for my computer to realize that the site is no longer under maintenance. Isn't there another way to do these updates without breaking this?
get better dns server. im not trolling, but this is a real answer.
try using servers 4.2.2.1 and 4.2.2.2
These will resolve the site quickly in under an hour for ip changes. our last ips were blacklisted by some internet service providers, and this caused them to not deliver our emails such as registration confirmations, lost passwords, etc. we got new ones to avoid this n the future.
sorry for the inconvinience.
