Twitter and GitHub have been down for me for a while now.

You can use this to find IPs for services that are currently out: https://dns.google.com/query?name=github.com&type=A&dnssec=t...

TIL about dns.google.com. Seems to be pretty handy for doing quick lookups. Thanks Mizza!

they're not down you just can't resolve the URL

as a temp solution, add these to your /etc/hosts file: 192.30.253.113 github.com 151.101.44.133 assets-cdn.github.com

I navigated to the IP address for Github, but it still tries to resolve to github.com

I'm kinda surprised at how bad the OSs deal with this. If you can't get a DNS lookup, would it be so crazy to use the last-known cached value for it?

There's no reason for a computer to not be able to find a site I've been visiting every day for the last year. DNS data should be cached for at least 48 hours -- TTLs should be set to at least this.
