Summary
Nuday Networks Inc.
hosting legacy
A colocation and network operator (NUDAY), Nuday Networks Inc., running a data-center facility in the Toronto area.
What it's used for
- Colocation, transit, and hosting, with multiple Tier 1 upstreams (Cogent, Zayo, GTT, Arelion) for redundancy.
Notable
- A commercial hosting/colocation network rather than an institutional one.
Interesting
- A recent BGP network holding a low AS number — the number was reissued to its present holder, so it does not reflect an early-internet allocation.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,779 prefixes, as published 2026-10-21. 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.
