Summary
Centersquare
hosting colo datacenter legacy
The colocation network of Centersquare, the data centre operator assembled out of the former Cyxtera and Evoque estates.
What it's used for
- Carrier-neutral colocation and interconnection, with address space assigned to tenants inside the facilities.
Notable
- 46 observed BGP neighbours against only 40,000 addresses. That inversion is the signature of an interconnection business: the value is in how many networks meet inside the building, not in how much address space the operator holds.
- One block sits in RIPE rather than ARIN, registered to Cyxtera Technology UK Limited under the netname
UK-CYXTERA-20181219. Cyxtera was the company spun out of CenturyLink's data centre business in 2017 and broken up in 2023, with the facilities ending up under the Centersquare name. The 2018 date is baked into the netname.
Interesting
- Data centre estates change hands far more often than the networks inside them get renumbered, so a colocation AS accumulates registry records naming every previous owner. Here the announcer, the ARIN registrant and the RIPE netname are three different companies in the same lineage.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
