Many of our projects are using SVN just because it's the easier one (at least until lately) to configure and set up locally. So that's a small win for SVN, and removes the issue of GitHub being down.
The real problem that we should be talking about is - Pull request based workflow many companies (including mine) have adopted. Which doesn't work when github goes offline.
I hear from lot of teams, they have switched to using github issues for project managment entirely, so as pull request and tickets can be "seamlessly" linked. That goes out of window as well.
But yes, you are right. Being able to copy it from my neighbor is nice.
The company I worked for used GitHub as the source for its build systems releases. If you can't do releases because GitHub is down a few times, I'm sure the dev/ops team will start looking elsewhere.
Tomorrow Bitbucket can get under the same attack.

You are blaming Github for being attacked by DDOS?
And, in my experience, they'll very freely give you 1-2 month temporary packs, even if you're late with the renewals. Very good customer service.
