In my access logs, I found requests from a user agent I had not seen before: InternetPressureProbe. The link in the user agent leads to InternetPressure.io, which calls itself “the real-time pressure gauge for the Internet”.
The site scores routing, latency, DNS, availability, HTTP/TLS and path data from 0 to 100 and weights them into one index. This is the user agent from my logs:
InternetPressureProbe/0.1.0 (+https://www.internetpressure.io/probes)According to its probe page, the probes are lightweight Go agents that run HTTP, DNS, ping and traceroute measurements. At the time of writing, there were eight probes in locations such as Montréal, Québec City, Gravelines, Dublin, Istanbul and Atlanta, hosted at providers like OVHcloud, Bell Canada and MacStadium.
The page says the probes “never scan, never bypass anything and never send more traffic than a normal user would”. It does not mention robots.txt or a way to opt out.
I hope this blog post will help you identify this bot in case you also find it in your logs and were unaware of its origins.
