No, someone intentionally or accidentally used gox's poor handling of mutant transactions to extract double-payment from their customer support team. Gox blamed the bitcoin protocol for their own stupidity. Then after the press release, someone started a massive DoS attack against the bitcoin network. What happened to gox over the last couple of months is totally different from what what is going on right now.

No, you are wrong, sir. There are many who are recording all Bitcoin network traffic, myself included. I can see that Gox had all their outbound transactions slightly changed and rebroadcast. After that went public, being now outed and in the open, having nothing to gain from stealth the attacker moved to attacking everyone they could.
