I thought DNS (particularly public) was basically immune to DDoS?

If one DNS server is down, use the cached result or another server.

DNS is some of the most distributable, cachable data I can imagine.

Earlier quoted context omitted.

Can we add a line to our /etc/hosts file with a hard-coded DNS entry to fix it in the meantime? What's the IP address?

I looked up an ip for twitter (via a google search) and still timeout on pings. [edit: twitter and github are both accessible again.]

For me it resolves to 192.30.253.113

Indeed. How can it be so broken? And, it seem that it would make sense to use the last known value if upstream is unavailable.
