Having trouble accessing PayPal, NewYorkTimes.com, Twitter, Reddit, PlayStation Network (we know you were trying to play Skyrim today — don’t lie) or another major website or network today?

Apparently, hackers have been attacking one of the internet’s biggest hosts, Dyn, with a distributed denial of service (DDoS) assault.

And it appears as though the Zillow Group sites are among those who use Dyn servers to host their content.


This error message is currently appearing for both Zillow and Trulia.

An Inman reader on the Coast to Coast group also reported that the Arizona Association of Realtors eSign business tool, which is powered by GoPaperless, is being affected by the hack — no doubt other signature and productivity tools could be affected, too.

Dyn’s latest update about the attack was at about 12:45 p.m. PDT today. You can keep yourself posted about the host’s progress at that link.

What’s the point of a DDoS attack? Some reasons why hackers use them include:

  • To express displeasure against specific targets
  • To take down a competitors’ website
  • As an extortion technique — “Pay the ransom or we’ll take out your website”
  • To divert attention from another activity that the hacker might be doing — such as stealing data

It’s not clear what the purpose of a hack this size could be.
