I fully believe this was a DDOS attack. But, this is good advice. If you think you're getting DDOS'd, check for the number of unique IPs against your own user pool. Probably a lot more people introduce bugs into their codebase that DDOS's their own app than get repeatedly targeted by a well-funded attacker as above.
