Planned Maintenance Process

Step 1: Change Request

All planned maintenance must be approved through the Change Advisory Board (CAB) before any communication is issued. The change owner submits a Request for Change (RFC) through the IT Service Portal at least 10 business days before the proposed maintenance window.

Step 2: Communication Planning

Once the RFC is approved, the change owner completes the Outage Communication Template (available on the IT Service Portal) with the following information:

  • System(s) affected
  • Date and time of maintenance window (including timezone)
  • Expected duration
  • Impact description (what users will experience)
  • Workarounds available during the outage
  • Rollback plan summary
  • Contact point for queries

Step 3: Notification Schedule

Unplanned Outage Process

Step 1: Detection and Assessment

When an unplanned outage is detected (via monitoring alerts, user reports, or SOC notification), the IT Operations duty manager assesses the impact and assigns a priority level in accordance with the IT Incident Reporting Procedure (IT-INC-001).

Step 2: Initial Notification (within 15 minutes)

For P1 and P2 incidents, the IT Service Desk issues an initial notification within 15 minutes of detection. The notification includes:

  • Affected system(s)
  • Nature of the issue (to the extent known)
  • Current impact
  • Estimated time to resolution (if known) or next update time

Step 3: Ongoing Updates

PriorityUpdate FrequencyChannels
P1 — CriticalEvery 30 minutesStatus Page, Teams, Email, SMS
P2 — HighEvery 60 minutesStatus Page, Teams, Email
P3 — MediumEvery 4 hoursStatus Page, Teams

Step 4: Resolution and All-Clear

Once the issue is resolved:

  1. The IT Status Page is updated to "Operational" with a summary of the issue and resolution.
  2. An all-clear email is sent to all previously notified stakeholders.
  3. A brief post is made in the Teams #it-status channel confirming resolution.
  4. For P1 incidents, a preliminary Root Cause Analysis (RCA) summary is distributed within 24 hours, with a full RCA report following within 5 business days.

IT Status Page

The IT Status Page is the authoritative source for real-time information on system availability. It is accessible at status.globalbank.com and displays the current status of all major systems and services. Employees are encouraged to check the Status Page before contacting the Service Desk during a suspected outage.
