PagerDuty has shifted from using Twitter to a status page for communicating about major outages, following a significant AWS cross-AZ failure in the US-EAST region. To enhance communication during large-scale issues, they are developing an opt-in notification system that is separate and external. Meanwhile, they advise users to subscribe to their PagerDuty Status page for updates. Although they plan to rarely use Twitter for updates, users can still receive direct notifications from the PagerDuty Ops team by enabling mobile notifications for the @pagerdutyops Twitter account. Detailed instructions are provided for setting up these notifications, emphasizing the importance of staying informed about potential disruptions in PagerDuty's notification services.
