There is  a routing problem  at PSU's  provider which prevents  them from
communicating with  LSOFT.COM. A lot of  lists are affected and  a ticket
has been opened.  This morning I have been unable  to contact DIGITAL.COM
for several  hours, due  to a  similar routing  problem. As  the Internet
grows, incidents such  as this one are unfortunately unlikely  to go away
as there  is a finite  pool of  experienced router managers  whereas ISPs
must face explosive demand.
