What channels were used for alerts?

Alerts typically use several channels to ensure timely notification of the team:

• Email — for formal notifications and reports.
• Messengers (Slack, Microsoft Teams, Telegram) — for quick information sharing and discussion.
• SMS or calls — for critical incidents requiring immediate response.
• Monitoring systems with built-in alerts (Prometheus Alertmanager, Zabbix, Datadog) — for automatic creation and sending of notifications.

The choice of channels depends on the importance of the incident and the team's preferences.
