6,748 domains added. 803 removed. AdGuard DNS Filter leads the week with 2,902 new blocks and 357 removals. EasyList added 844 domains and removed nothing. Several removals this period signal quick reversals—always good for a double-take.
Jumia Kenya Subdomains: In and Out in a Day
125.net.jumia.co.ke and 68-175.net.jumia.co.ke were both added and then removed from AdGuard DNS Filter and AdGuard Tracking Protection Filter, all on October 13. Why does this matter? If you rely on Jumia's infrastructure for analytics or integrations, you may have noticed brief breakages or missing data. These kinds of whiplash removals usually mean the block was a false positive—possibly triggered by a pattern match gone wrong or a mistaken bulk addition. Worth double-checking if you saw sudden traffic dips or unexplained outages.
Analytics Subdomains Get a Reprieve
analytics.andersonsatori.com.br and analytics.firstbankcardcenter.com were both removed from AdGuard DNS and Tracking Protection lists. Both were only added on October 13, then pulled almost immediately. For teams using these subdomains for legitimate analytics, this means full tracking should resume. If you saw dropouts, this wasn’t a user revolt—just a list editor with a quick trigger finger. If you operate analytics on branded subdomains, it’s a reminder: list maintainers don’t always get it right, but they sometimes catch their own mistakes fast.
High-Consensus Block: darngavel.com
darngavel.com hit four major lists at once: AdGuard DNS Filter, AdGuard Tracking Protection Filter, EasyPrivacy, and Peter Lowe’s. When a domain gets this much attention, it’s not an accident. Marketers and devs: if you see traffic routed through this domain, treat it as radioactive. This kind of alignment means users with any mainstream blocklist will never see requests land. If you’re trying to keep a tracker alive, pick a different name (but expect the same fate).
Pattern Watch: The Rise of "Rest" and "Cfd" Trackers
EasyList saw a flood of domains like 1gcke6g87481v6mk2uggxj6.rest, 1r3vwgu3wofhymygetop97rf.rest, and 33p3v9fte86o99kl9gqf7wnb7eu3v85u.cfd. The pattern: long, random subdomains on cheap TLDs like .rest and .cfd. This is classic short-lived tracker or malvertising infrastructure. For engineers running allowlists, know that entire ranges like these are getting swept up. If your SaaS or CDN shares a TLD, expect some collateral damage.
