Summary
Northern Data
hosting hpc colocation uk
HYDRO66 is operated by Northern Data.
What it's used for
- The address space carries HPC and colocation infrastructure, evidenced by netnames such as
UK-HYDRO66-20200527and registrants includingH66Cloud Abuse. - The AS announces 3072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 22 observed neighbours; this ratio indicates a hosting and infrastructure provider rather than a transit carrier.
- Traffic from this AS consists of high-performance computing workloads and data centre colocation services, consistent with Northern Data's business focus on HPC infrastructure.
Notable
- Registrants across all announced prefixes consistently identify
NORTHERN DATA SERVICES (UK) LIMITED, aligning with the current operator identity. - Hydro66 was sold to Northern Data in March 2021, a specialist HPC infrastructure company listed on the Deutsche Börse, leading to the rebranding of the service.
- The inventory comprises three /22 IPv4 blocks and a single /29 IPv6 prefix, representing a compact estate typical of a focused HPC provider.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 451 networks and 1,853 prefixes, as published 2026-11-04. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
