Summary
Digital Fortress, Inc.
hosting legacy
The network of Digital Fortress, Inc. (DF-TUKWILA01), a carrier-neutral data centre and colocation provider headquartered in Tukwila, just south of Seattle, Washington.
What it's used for
- Colocation, network and cloud-access services for enterprise customers, served out of Digital Fortress facilities in the Seattle area and beyond.
Notable
- Hosting and colocation address space, so addresses here front customer servers rather than homes or offices.
- The handle names the company's Tukwila site, its headquarters and network operations centre, sitting on the Seattle-area internet campus that anchors much of the region's interconnection.
- ARIN registered AS3361 to Digital Fortress in 2009, so despite the low number this is a modern data-centre allocation rather than an early-internet one.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
