This document explains Flow Production Tracking’s policy regarding maintenance, releases, and other disruptive events.
Non-disruptive maintenance: A maintenance operation during when the Flow Production Tracking service is still available (no downtime) or that result in less than 2 minutes of downtime.
Disruptive maintenance: A maintenance operation that results in less than 10 minutes of downtime.
Highly disruptive maintenance: A maintenance operation that results in more than 10 minutes of downtime.
Emergency maintenance: A maintenance operation that must happen as soon as possible.
All disruptive operations, and sometimes non-disruptive ones, are announced on our Status Page. Clients can subscribe to that status page to receive notifications about maintenance events.
Highly disruptive operations are also announced using a banner in the Flow Production Tracking web application.
Whenever possible, disruptive maintenance windows will be announced at least 24 hours in advance.
We make every effort to ensure this maintenance schedule:
| Type | Preferred window | Status page announcement | Banner |
|---|---|---|---|
| Non-disruptive maintenance | Weekdays 3AM PT – 5AM PT | At Flow Production Tracking discretion | No |
| Disruptive maintenance | Sundays 6AM PT – 8AM PT | Yes | No |
| Highly disruptive maintenance | Sundays 6AM PT – 8 AM PT | Yes | Yes |
Flow Production Tracking reserves the right to execute emergency maintenance at any time, and to modify this schedule without notice.
Flow Production Tracking releases are rolled out on a per-site basis, throughout the maintenance window. The exact time at which a site will receive a new release is nondeterministic.
| Type | Preferred window | Status page announcement | Banner |
|---|---|---|---|
| Non-disruptive release | Weekdays 3AM PT – 9AM PT | Yes | No |
| Disruptive release | Sundays 6AM PT – 12PM PT | Yes | Yes |
| Major feature releases | Sundays 6AM PT – 12PM PT | Yes | Yes |
