What domains are false positives?

f005.backblazeb2.com
ecsomag.hu
serverelite.hu

Why are they false positives?

I maintain a downstream Pi-hole list that consumes this blocklist, and these three came through as false positives. Details:

f005.backblazeb2.com — Backblaze B2 core infrastructure, not a user-owned bucket. It's the shared download / native-API host for the us-east-005 storage cluster:

• Resolves into Backblaze Inc IP space (149.137.136.16, NetName BACKB-7).
• GET /file/<bucket>/... returns Bucket with such name does not exist — the bucket is taken from the path, so one host fronts every tenant in the cluster.
• GET /b2api/v3/... returns a valid native B2 API response.
• Blocking it breaks B2 downloads/backups for all customers on that cluster. Individual abuse buckets have their own <bucket>.s3.us-east-005.backblazeb2.com hostnames, which are unaffected.

ecsomag.hu — "GLS eCsomag", GLS Hungary's official parcel-sending portal:

• IP 82.141.140.12 → whois "GLS Hungary Kft." (NetName GLS, HU).
• Authoritative nameservers ns1.gls-hungary.com / ns2.gls-hungary.com.
• Registered 2015; live GLS-branded service.

serverelite.hu — ServerElite (operator MARAELITE Kft), an established Hungarian retailer of refurbished enterprise servers:

• Domain registered 2017, Microsoft 365 business email, full company identity (Budapest address, Dell Gold Partner, ISO 9001/14001/27001), card payments, real OpenCart storefront.
• Named by Financial Times / Statista among Europe's fastest-growing companies (2024).

Thanks for maintaining the list.
