Well, I had Linode shortlisted for an upcoming project. I hate to take them off the list because it is not their fault, but I don't want this kind of unreliability.

Atlanta is their smallest datacenter IIRC with their lowest bandwidth capacity. I would still recommend them as we have had great luck with their Dallas DC. It seems to be the most resilient of them all in terms of random network outages and also DDOS attacks. However the one in December did take them offline for a few hours but after which they apparently implemented more DDOS protection. Keep in mind this could hap…

>the one in December did take them offline for a few hours

That is a bit of an understatement. Our servers were down every couple of hours for a week, and the attack bounced around to pretty much all of their datacenters.

Sorry I should have clarified. Our servers were down for a total of 4-5 hours spread across a week or so. After the first incident it only took a few minutes for them to come online each time, although I hear others had varying downtimes while they mitigated that DDOS.

Thankfully it was over Christmas time so our clients were mostly offline.

Does the US have a competent cyber-crime division that can handle stuff like this?

Yes, the FBI. They're fantastic at it and part of their job is helping businesses recover from compromise and going after the attackers. However, they're overworked government employees with not enough resources.

How did you set it up to failover? Our MySQL database is very large, and I'm not sure of the best way to ensure it is up to date on another host.

For our setup we just have master-master replication across two different hosting providers.

I've been wondering about this lately. Is it really feasible for a small (one man?) team to keep master-master MySQL replication over WAN running smoothly?

Can anyone recommend a good article that explains how attacks like these work, and what is required to stop them? Also, we're on Heroku and they advertise Ddos mitigation as a feature, but "mitigation" sounds non-commital and I'm curious how they'd fare against a similar attack?

Cisco has the easiest to grasp fundamentals [1], but to really understand DDOS attacks you'll have to dig down into learning about how TCP works and network layers.

Mitigation sounds non-commital because it is. I don't personally have any experience with mitigating a DDOS attack on Heroku, so I'm not qualified to talk about their prepardness, but DDOS mitigation varies quite a bit [2][3], running the entire gamut of "block a single IP address" to "there's hundreds of IP's rotating and attacking". So the answer to that would be: it depends on who you've pissed off or who's feeling particularly nasty that day.

I used to be on Linode... then one of their techs tripped on a power cord causing a significant outage in a data center... and no I'm not joking.

with linode for 10+ years and never heard about this, can you back this up with some evidence?
