Ask HN: What is it with the recent DDoS attacks on Linode?

Linode has been experiencing a wave of DDoS attacks in the last few days. I've noted connectivity issues at Newark and London datacenters. DDoS isn't something of a novelty, but being a Linode customer for several years now I don't recall having that much of a problem with availability before. Is this attack of any special significance?
