Abuse reports cover things like spam, port scanning, malware distribution, or copyright complaints originating from your IP space.
When we forward one to you, please respond within the stated deadline (usually 24 hours). Identify the host, contain the issue — isolate or rebuild a compromised machine — and reply describing the remediation.
Prompt cooperation almost always avoids escalation. Unaddressed serious abuse may result in a temporary null-route of the offending IP to protect the wider network, but we'll always try to reach you first.
