My startup cucumbertown.com is hit with similar issues.

Initially we blocked all Ec2[1] & spamhaus ip list. But then realized Flipboard proxies[2], some blog aggregation proxies etc are based on Ec2 machines.

What would be a good way to block such rogue machines? Is there a community sponsored list or Ec2/Rackspace ips that are creating issues?

Banks were being hit the first week of October, then I know some VoIP servers were being hit such as Callcentric by DDoS. I can see why the banks were hit, but not why so many much smaller businesses are being attacked.

I would think being small(er) and having 100M in the bank makes github a pretty good target, unfortunately.
