Jetpack DNS Query fails

Apparently the problem is not with the update, its appearance just coincided with my renaming the local instance from .local to .abc, because I read that localWP has performance issues on domains like .dev and .local, which turned out to be true.

Apparently, since .abc is not a known local domain, the jetpack code you use in your plugin, now attempts to check and guess the host/type based on DNS, but that appears to fail. I normally wouldn’t care about the error, but the failing DNS query adds about 5s to the loading time.

I can reduce that by turning off the guessing attempt by setting

'host' => ( new Host() )->get_known_host_guess( false ),

in line 167 of class-script-data.php, but there’s no way to do this without changing core plugin/jetpack code.

I don’t know if it’s possible to turn this behaviour off in your calling of the Jetpack code or if it’s a required functinoality. Neither the failing DNS request nor the disables one seem to have an influence on the functioning of the social feed once it’s loaded, so if it’s a configuration aspect you could disable in your use of the Jetpack code, maybe that’s an option.
