Jackson County has different SLAs/maintenance windows for different systems
depending on who uses them and when they normally work. We have such diverse
customers that there is no one-size-fits-all window. For example, the Roads
fleet maintenance system can be taken down without notice anytime from 6pm Fri
to 6am Mon because they never use it on weekends. ERP window is any Saturday
night without notice, but we try never to take the Jail down on a Saturday
night because it's their DUII rush hour.
Maintenance on general systems like email, etc. can happen any Tue or Thu
evening from 6:00-9:00 pm so long as a notification goes out by noon that same
day. If the maintenance will be particularly disruptive, or has to happen
outside the regular window for some reason, we provide 2 business day advance
notice.

Hi Dave,
Good to hear from you.
We have a monthly maintenance window on the second Wednesday starting at
5:30PM. Which means we had one last night. This effort covers all systems and
networks including Regional Law Enforcement and Jail. It excludes 911 who
provide their own support. We pre-plan the maintenance effort and bring down
only the systems necessary, with only the staff necessary. Typically tasks
queue up pretty quickly so there's plenty to do. The time window for
maintenance varies, but it's typically around 2-3 hours. We announce the
expected up time in a reminder email to everyone. Last night's was estimated
to be from 5:30 to 7:30 and we were back up by 7:15. Here's an example of the
content of the email we sent on 2/11:
The Deschutes County IT department will perform routine computer system
maintenance, Wednesday from 5:30pm to 7:30pm. All central systems will be
affected, some only briefly, during the maintenance period. NOTE: 911
Operations will NOT be affected. If you have questions or concerns, please
contact...
We feel it would be difficult and disruptive to do maintenance any other way
and our users are cooperative.

Hello fellow Oagitm's
Clackamas County Technology Services is a 24/7 operation supporting everything
in the world with less staff and no budget and everyone expecting 100% uptime.
Sound familiar? In the middle of this utopia world of expectations we live in
we have found it necessary to schedule one Saturday a month to do preventative
maintenance. On these days we do things like storage migration, hardware swap
outs, patch upgrading and whatever else we need to do that requires us to take
servers down or at least exercise contingency processing procedures for
critical systems (Sheriff's Office, 911 Center). This doesn't mean that we
bring everything down but there are areas that are affected with service
interruption during this process.
So my real question is: (finally!) Do you have scheduled maintenance days and
what is the frequency? Monthly, bi-monthly, quarterly?
Thanks in advance for all your wonderful input!
