Data from the past few days we do have a legitimate interest in; protecting our network. If someone is spamming us we need to be able to find out who did it and the only way to do that is deanonymized logs to begin with. Atleast in my workplace we have worked with the DPA to ensure that we are in compliance and there is no issue in keeping around 7 days of IP logs without further anonymization. All or long term logs are hashed below the bit minimum, and that can't be paired with old request data as easily since we strip all but major version identifiers from User Agents, for example.
