Adjust is currently experiencing a service outage. The issue has been identified as a DDoS attack and a fix is being implemented. While the issue is present, a significant portion of Adjust tracker URLs can fail to redirect, all incoming engagements and s2s requests aren't processed in full. Requests such as installs, sessions, and events sent by the Adjust SDK are not being processed but they will be buffered locally on each device and replayed in full once our services are back online. We sincerely apologize for the disruption and inconvenience caused.
