End-of-Support Schedule for Unix Systems

Date of last revision: 03/06/2001

As much as we'd like to keep computers running forever, it isn't always practical. Software and hardware support becomes more and more scarce as systems get older, while hardware failures become more common. Old systems also slow to a crawl trying to run the newest software.

Because of this problem, old systems will not be supported by Engineering Computer Support Services (ECSS). If you wish to continue using a system beyond its end-if-support date, you must maintain the system yourself, and it may not be part of the main Engineering Unix system.

We have tried to be as generous as possible in scheduling end-of-support dates. Please let us know if you feel that we have set an end-of-support date too soon. We will also consider making exceptions on an individual basis as long as you have another plan in mind.
