INC-3723 (P1 - High Priority)

Incident Report for Yoti

Postmortem

Sunday 10th May 2026 - Tuesday 12th May

We are pleased to confirm that all Yoti services have returned to normal operation following a period of service instability.

Starting on the evening of May 10th, our network was targeted by a highly orchestrated and large-scale distributed DDoS attack. This was a coordinated attempt to overwhelm our systems with high volumes of traffic, which resulted in intermittent outages and access issues across our platform.

We would like to reassure you that this was a connectivity-based attack. At no point was the integrity of our core systems or your personal data compromised.

To resolve the issue and protect against future attacks, we have:

  • Successfully migrated our network traffic to a global, industry-leading protection service (Cloudflare).
  • Implemented enhanced filtering to block malicious traffic before it reaches our services.
  • Increased our infrastructure capacity to better handle unexpected traffic spikes.

We sincerely apologise for the disruption to your service and thank you for your patience while our teams worked around the clock to resolve this.

Resolved

All Yoti services have been restored to normal operation. The recent disruption caused by a targeted DDoS attack was resolved through the implementation of enhanced network security and traffic filtering.

Our systems are now operating under reinforced protection to ensure continued availability.
Posted May 12, 2026 - 15:54 UTC

Update

We are pleased to report that all services are currently returning to normal operational levels. Our technical teams have successfully identified and implemented a permanent fix; as a result, core functionality has been restored across our entire product suite.

Whilst systems are stable, we are entering a period of extended monitoring. We will be closely tracking all products and user sessions to ensure that performance remains consistent under full load.

We intend to officially mark this incident as Resolved once we are confident in the long-term stability of the environment.

Should you experience any performance issues, please reach out to our Customer Support Team.
We appreciate your patience whilst we worked to restore your service.
