While the sks-keyservers.net domain and many of the old hostnames that powered it are dead & gone, the actual SKS keyserver network does in fact live on, complete with new & improved DOS mitigations and active development of the underlying server software powering it, Hockeypuck. More information can be found @ https://spider.pgpkeys.eu/ & https://github.com/hockeypuck/hockeypuck respectively.

Keyserver.ubuntu.com also exists, but has fallen out of sync with the network and to date has been unwilling to reengage.

pgp.mit.edu has been sporadically available for me over the last while, but yea AFAIU sks-keyservers 
shut down after the DoS drama, as did most of the old servers in the pool.

I believe keyserver.ubuntu.com generally works and doesn't strip all the signatures and whatnot off 
keys when they upload.

I think the hipster thing to do now, though, is --auto-locate-key with the Web Key Distribution or 
the DNSSEC Key Distribution mechanism.
