Customer impact for users that happen to use the 18.104.22.168 IP address for logs7.papertrailapp.com:
1. Port-Based Log Destinations and UDP users Logs would have been dropped.
2. TCP users Logs would have experienced a 6-hour delay, then sent all at once around 09:35-40 UTC. This delay will lead to incorrect timestamps in the logs, reflecting the time of arrival rather than the time of generation.
Importantly, there is no impact on Heroku customers and those utilizing logs7.papertrailapp.com as an HTTP log destination.
