Is my site blocked on Plus in Poland?
Plus, run by the company Polkomtel, blocks the domains on the Finance Ministry's register of illegal gambling sites and on CERT Polska's list of phishing domains. Customers who pay for Ochrona Internetu ("internet protection"), a security service Plus provides with the security company F-Secure, can have more pages blocked. If a Plus customer cannot open your site, search the two public lists first, then ask whether that customer has the service.

We open it through home connections of Orange, T-Mobile, Play and Netia and mobile connections of Play and Plus, the way their customers would, and tell you provider by provider whether it opens. Free, about a minute, a few checks per hour.
Which official blocks does Plus apply?
The same two national lists as Poland's other big providers. Every internet provider must send visitors of a domain in the gambling register to a Finance Ministry notice saying the site offers gambling illegally. Polkomtel, as the operator of Plus, signed the March 2020 agreement under which providers block the domains on CERT Polska's warning list in their DNS (the internet's address book, which turns a domain name into a server address). The details of both lists are on our Poland page.

In June 2022 the security site AVLab ran CERT Polska's own test, lista.cert.pl, on a phone on Plus's mobile network with Wi-Fi switched off, and the test found the list in use. The same test on a home connection using Google's DNS service found no protection, which is a reminder that a visitor's DNS settings change what they see.

What is Plus Ochrona Internetu?
Ochrona Internetu is a paid add-on, not a default. A customer adds it when ordering a mobile plan, mobile internet or fibre, or switches it on later by text message to 80088. Plus says the service is provided by Polkomtel together with F-Secure and is built on F-Secure Total. It includes network protection that works automatically while the customer uses the internet, with nothing to install, and Plus says it "blocks access to pages that may phish for data or contain malware". The larger packages add an app for several devices.

Who can lift a wrong block on Plus?
It depends on which list your domain is on. For the gambling register, the domain holder can object to the Minister of Finance. For CERT Polska's list, the objection goes to the head of UKE, Poland's telecom regulator. Both have deadlines and formal rules, set out on our Poland page.

For Ochrona Internetu, Plus documents no route for site owners. F-Secure, whose technology the service runs on, has a sample submission form that accepts a URL with the problem type "Harmless webpage is blocked (False Positive)". abuse@plus.pl is the network's abuse contact listed in RIPE, the public register of European network operators; it is not described as a way to contest a block.

How can I check my site on Plus myself?
Search your domain on hazard.mf.gov.pl and in CERT Polska's list, which you can download as plain text. Ask a Plus customer to open lista.cert.pl on mobile data with Wi-Fi off: it shows whether that connection uses CERT Polska's list. If your domain is on neither list, ask whether the customer has Ochrona Internetu switched on. Why a warning in front of your page costs you visitors: red warnings and lost visitors.

What does linkspect check on Plus?
We open your URL through the mobile connections of Plus customers; Plus home lines are not part of the check. A block in the DNS on Plus mobile is reported as "likely" at most, because we see only what the customer's phone received. Other Polish providers: Play, Orange, T-Mobile and Netia.
