Anyone else seeing this?

E: Failed to fetch http://security.debian.org/pool/updates/main/l/linux/linux-headers-3.16.0-4-amd64_3.16.36-1+deb8u2_amd64.deb  Could not resolve 'security-cdn.debian.org

Any suggestions?

I was seeing that too.
Tried again, this time through a VPN, and it worked.

It was apparently temporary. Worked when I got home from, well, work.

In case you don't know by now, it was probably this:

http://www.theregister.co.uk/2016/10/21/dns_devastation_as_dyn_dies_under_denialofservice_attack/

There were apparently at least 3 major phases of attack, with calm
between.
