Sb under DDoS attack

You, my readers, have been complaining about flakiness in Sb that goes above and beyond the usual technical flakiness of the site. So have many other readers, in particular PZ’s. After a couple of days where the blog loaded slow as the proverbial molasses in Minnesota in January, our benevolent but not particularly communicative overlords have finally revealed to us the reason for our problems:

We have been forwarding reports from bloggers and users to our hosting service, Rackspace, over the past few days. After monitoring our traffic and these reports, Rackspace has determined that ScienceBlogs is experiencing a distributed denial of service (DDoS) attack and has blocked a range of IP addresses involved. While this means that ScienceBlogs is now loading correctly for most users, the attack is still ongoing and other users may still encounter sporadic loading problems, or be blocked entirely if they were incorrectly included in these preventative measures.

We’re still working with Rackspace to determine how and why this has occurred, and to get the site 100% accessible again, but in the meantime, we’d like to collect IP addresses from users who are still experiencing problems. Please ask anyone who has brought this problem to your attention to send their IP address to If they have trouble locating their IP address, you can send them to this site:

Please also let us know if you are having any trouble accessing the backend of your blogs.

Hackers. Why’d it have to be hackers? I wonder if Orac finally ticked off some anti-vaccinationists enough that they’d go and do something like this, although for some odd reason PZ seems to think he’s at fault.
