Re: Maintenance Window(s) Procedures

[Buz Dale <buz.dale () USG EDU>]

 We have projects with differing uptime requirements,  Things like
firmware upgrades to routers and firewalls that affect multiple projects
are schedule during the downtime windows of the applications that are
impacted.
  We also try and use maintenance windows and notifications if we are
doing things that *might* impact an application.  Firewall rule changes
or routine config changes to core switches are schedule to minimize
those uh-oh moments.

We typically consider it maintenance if we make changes that could
inadvertently impact any service we consider "production." Those are
things like distance learning, network connectivity, payroll, etc.

Thanks,
Buz
