As had been the case late last week, we continue to experience a load issue on our main Grad Net mail and dept. DNS server.  This might be a hardware-related problem.  We will be applying some patches that might help with the issue, and as part of the procedure, we will need to do a system reboot ''and'' reconfiguration.

Weather permitting, we plan to begin the reboot/patch application process on Wednesday morning, 2/18, starting at 9am (at a time when we can reach the hardware vendor, if necessary.)  Again, this process will last up to an hour.
