It is easy to test sites locally on Windows and Macs.
127.0.0.1 domain.com to your hosts file to set a domain to localhost. This is commonly used to block domains.
I have been using this technique for years, without any problems.
However, I was always connected to the Internet, while I worked on local sites.
Where's the Internet?
I am staying with a friend who has lousy Internet service. Service works for hours, before it slows down, and finally disconnects.
Network reconnects in 10-20 minutes. It is not helpful to call tech support, and it does not bother my friend.
WordPress crashed when I tried to debug a local site, without an Internet connection. Unplug your Internet cable to follow along on your local site.

WordPress for Everyone
It is important to keep WordPress and plugins updated. But it should be easy to define a variable that prevents WordPress from attempting to update itself.
Anyone with a laptop should be able to debug a WordPress site, without an Internet connection.
There are people who rely on an Internet connection at a school or library. They should be able to debug a blog at home, and upload it to a server later.
I propose adding
WP_LOCAL should prevent WordPress from loading external resources.
I also waited for connection failures from gravatar.com, fonts.gstatic.com, fonts.googleapis.com. I do not use Gravatars or external fonts. Were these connections from WordPress or plugins?
This is not new.
Two similar WordPress tickets were opened and closed. Timeout to WordPress API in update.php was closed 13 months ago. Increase timeout for ‘plugins/update-check’ API request was closed 7 months ago.
WordPress users know if they are connected to the Internet.
WordPress could fix the login problem, by not triggering an error to say, “Please contact your server administrator.”
I am the server administrator. I want to login and debug a WordPress site, without an Internet connection.
