I've just posted on our forums the following:
We just began (less than 1 minute ago) began to see some PL across the Pegasus and DedicatedNOW network. We are already working on tracking down & resolving the problem with NAC, this is just a preliminary notification that there most likely are some issues currently underway. Anthony will hop on & post when he has a more definitive answer.
We will continue to alert / post any updates that we have, but are already aware, and on top of any issues.
