Maybe it broke when they updated their forum?

Anyway, here is their RSS post:

EINSTEIN@HOME DISCOVERS A RECORD-BREAKING PULSAR-NEUTRON STAR SYSTEM

Submitted on 9 Dec 2016 08:31:51 UTC
Recently, a new paper about an exciting discovery from our radio pulsar search has been published. In “Einstein@Home Discovery of a Double Neutron Star Binary in the PALFA Survey” we report together with an international team the most massive double neutron star system ever observed.

Read more about this topic in the publication itself, or in our accompanying press release.

Cheers,

Double Neutron Star Binary? Is that 4 stars? Or just worded poorly?
