[Feature Request] Fallback lookup when ident.me is down.

[lightlike]

ident.me was down for about a day and the container is throwing the following error.

Warning: file_get_contents(http://v4.ident.me): Failed to open stream: Connection refused in /app/updater.php on line 12
Fatal error: Uncaught TypeError: trim(): Argument #1 ($string) must be of type string, bool given in /app/updater.php:12
Stack trace:
#0 /app/updater.php(12): trim(false)
}
  thrown in /app/updater.php on line 12

It would be nice to have 1 or 2 fallback sites.
ident.merecommends this as well (see: https://api.ident.me/#redundancy-alternatives)

A drop in replacement would be tnedi.me.
This might also be a good starting point for this: https://gist.github.com/rkalkani/7428a8769f7cc6710c58680938dc5833

I can try to write some code for that if you want but I am no PHP Developer.
My code would probably just be a try catch that follows up with a request to tnedi.me.
