Feedly, the popular and free RSS service cannot be accessed for several hours because of a DDoS attack. The attackers are demanding money to stop the attack.
The danger of paying DDoS blackmailers is that you’re only encouraging them to attack you more, perhaps increasing their financial demands next time, so Feedly is really doing the right thing here by sticking to their guns.
What is a DDoS attack?
A DDoS (distributed denial of service) can be made in several different ways. For example, it’s called a DoS (denial of service attack) if a server has enough bandwitdh and enough resources, it can open thousands of connections to my blog and probably bring it down because it is effectively drowning it in requests.
With Feedly however, it is probably a botnet, which is a network of infected computers controlled by somebody. This network can have thousands of computers that receive the command to attack Feedly.com at the same time. This is the DDoS, as it’s distributed.
