postmortem
**Status update: Service disruption on 1 July 2026**
On Monday 2026-07-01, between 07:00 and 08:55 UTC, Lyyti experienced unavailability and degraded performance affecting Lyyti core, including Portal, registration pages, API, integrations and mobile apps.
Due to unforeseen circumstances, a high-traffic registration event triggered multiple edge cases in our system, resulting in significantly higher than expected load on our servers, which in turn caused slowness and disruption to our normal services. This was more than a routine traffic spike, and our team worked throughout the incident to restore full service.
As part of our post-mortem analysis, we have identified the underlying causes. We have since deployed fixes to mitigate the identified issues and prevent this from happening again.
We apologize for the inconvenience caused by this outage. If you have any further questions regarding this incident, do not hesitate to contact us.
We're currently investigating a major outage, no data is lost or corrupted.

Affected components
Messaging
investigating
Since approximately 8:40 UTC today, statuses for outbound email messages are not properly reflected in the messaging statistics in Lyyti Portal. This causes all messages to be shown as 'sent' regardless of the actual status. In other words, statuses like 'opened', 'clicked', 'bounced', 'blocked', are not currently reflected for most messages sent today.
Rest assured that messages are being delivered as normal, and the issue at hand only concerns the statistics and the visibility of statuses for specific messages.
We are investigating the issue together with the email service provider, and we will let you know once the issue has been resolved.
monitoring
The cause for the issue with the statuses has been located and the issue has been resolved. Email status updates are currently flowing normally, but it will take a moment for the statuses for the last few hours to be updated within Lyyti.
We are monitoring the situation and will close the incident once all statuses have been properly updated.
resolved
Retroactive email statuses that had accumulated during the day have been updated, and statuses are updating in real-time as of approximately 14:05 UTC. This incident has been resolved.
