How can we export Adyen logs to our SIEM with least-privilege scopes?

Rollback plan

• 1. Implement a multi-gateway architecture

To avoid a total payment outage, your system should be able to route transactions through multiple gateways. If you are migrating from an existing gateway, keep that gateway fully operational as a fallback option.

Smart routing: Configure a rule-based engine to send a percentage of transactions to the new PayU gateway. This allows you to monitor performance in a live environment without a full-scale migration.

Automated failover: Implement logic to automatically detect a performance degradation in the PayU gateway (e.g., increased latency, higher error rates) and reroute 100% of traffic to the previous or an alternative gateway.

• 2. Define clear rollback triggers

Establish specific, measurable thresholds that, if crossed, automatically or manually trigger a rollback to the previous payment system.

Transaction success rate: A drop of more than 2% in the payment success rate over a 10-minute period.

Gateway response time: An average response time increase of more than 500ms for a sustained period.

Error rate: A spike in 5xx HTTP errors or specific PayU-related decline codes.

Customer complaints: A sudden increase in support tickets mentioning payment failures.

• 3. Create a rollback procedure

A step-by-step guide is critical to a swift and clean rollback.

• Stop new PayU traffic: Immediately stop all new traffic from being routed to PayU by updating the smart routing configuration.
• Verify fallback system: Confirm that the failover to the existing gateway is working correctly and processing new transactions without issue.
• Deploy a hotfix (if necessary): If the regression was caused by a specific code change, prepare a hotfix for a quick redeployment.
• Monitor fallback performance: Continue monitoring the previous gateway to ensure it can handle the full volume of traffic.
• Perform root cause analysis: After the immediate crisis is averted, conduct a post-mortem to determine the precise cause of the performance regression.

Communications plan
The communications plan should be transparent, timely, and empathetic. Pre-drafted messages and a clear escalation path will save critical time during an incident.

• Internal communications

Notification: Establish an automated alert system (e.g., Slack or email) to notify key internal teams immediately when a rollback is triggered.

Incident team: Define an incident response team including a communications manager, technical lead, and customer support lead.

Internal status page: Maintain an internal status page to keep all employees informed of the incident status without distracting the technical team.

• External communications

Acknowledge the issue: If the performance regression significantly affects customers, use multiple channels to acknowledge the problem quickly.

Focus on customer impact: Translate technical issues into language that customers understand. Avoid jargon like gateway timeout and instead say, Some customers may be experiencing failed payments

Building comprehensive outage playbooks for bank maintenance windows that disrupt UPI and NetBanking requires a proactive approach focusing on preparation, clear communication, and efficient recovery.

• Pre-maintenance planning and preparation
• Communication strategy
• During the outage
• Post-outage procedures

To pilot the newest Outlook features this month without disrupting production, admins should enroll a select group of users in the Targeted Release program within the Microsoft 365 admin center. For organizations that have not yet migrated to the new Outlook for Windows, this also involves managing the rollout of the new client.
This approach allows a test group to receive updates up to 30 days before the standard release, giving IT time to prepare and adapt.

A rollback plan for Microsoft Teams performance degradation should include a multi-layered approach, ranging from immediate client-side troubleshooting to reverting administrative policies that control new features. The most critical first step involves isolating the issue within a targeted pilot group before broader rollout.

• Phase 1: Pre-deployment preparation
• Phase 2: Rollback procedures
• Phase 3: Post-rollback

Before enabling new Microsoft Teams features on mobile and desktop, it is critical to review and update Conditional Access (CA) policies to secure corporate data and prevent unauthorized access. Since Teams relies on other M365 services like SharePoint and Exchange, your CA policies must be consistent across these applications to avoid security gaps.
