On March 14, 2022, between approximately 16:00 UTC and 23:59 UTC, a small subset of EMEA Email Security.cloud infrastructure experienced a minor outage resulting in email delivery issues for some customers. Some inbound and outbound emails processed during the incident timeframe may have been irrecoverably lost. Note: the impact was less than 0.2% of email traffic during the impacted period.

We have identified the root cause and the deployment of the fix is in progress.

We can already assure that there was no impact to protection services and that no customer data was exposed to any risk of unauthorized access, disclosure or dissemination. No individual person's privacy was compromised or threatened at any point in time. Please rest assured that we will be implementing the necessary measures to prevent a recurrence of this issue.
