We are continuing to experience service outages resulting from changes to 
services (DNS/DHCP)made over the weekend.  The issue was escalated early 
this morning and continues to be worked on to resolve the connectivity 
problem many of you are experiencing.

As the problem is random, meaning your computer may connect, while the 
person seated next to you may not, it is very difficult to communicate to 
individuals whose service may already be restored.  We ask your 
cooperation in communicating this to those who are impacted as they will 
not receive this message.

If you are unsure as to whether your services have been restored, please 
shut down your computer and restart.  If everything works properly after 
the restart, then your services have been restored.  If not, your services 
may not be restored until end of business day or in some circumstances, 
tomorrow morning.

We do apologize for the inconvenience, but are doing everything possible 
to have all services restored as soon as possible.  We will provide 
further updates before 5pm this afternoon.
