Enterprise Services
Distributed Services Group (DSG) provides system administration for a number of services. Many
of these services are utilized by a majority of the organization or
represent core Information Technology resources. In order to
addequately support these services it is necessary to prioritize
the service primarily based on impact to UCAR/NCAR business continuity.
Associated with these priorities are also a set of service levels
defined below.
-
Severity One problems are paged immediately
7X24x365. Severity One problems are worked
on a best effort basis at the judgment and discretion of
DSG/Security.
No staff member will work more than 12 hours in a day.
-
Severity Two problems are paged out between the hours of
7am and 7pm seven days per week (except NCAR holidays).
Note: Severity Two problems occurring after 7pm are paged out
via email and paged out the next day if no response has been
received from the email notification.
-
Severity Three problems are sent out via email and handled
8am to 5pm, Monday through Friday, Next Business Day (NBD).
Priority One
Priority One services are viewed as mission critical to the organization. Also these
services tend to impact other services if unavailable. As such, any hardware or software
failure is deemed a Severity One problem.

Priority Two
Priority Two services are mission critical but typically to a smaller community or portion
of the organization. Also, because of the nature of the service it may be more fault
tollerant. Hardware or software failures that result in the service being unusable or seriously
impaired will be treated as Severity One. All other problems will be dealt with as Severity
Two.
