Hello, I'm a participant in dn42, an overlay network that experiments with Internet technologies such as BGP, OSPF, Babel, WireGuard, IPsec, and more. A while back, I added dn42.dev (one of the mirrors of the dn42 wiki) to OONI Probe. According to [1], Iran and Poland are blocking this site. I wanted to look at the specific measurements for Poland [2], but was unable to do so. Server Response { "name": "AxiosError", "message": "Network Error", "baseURL": "https://api.ooni.org", "url": "/api/v1/measurements", "params": { "probe_cc": "PL", "domain": "dn42.dev", "test_name": "web_connectivity", "since": "2026-01-01", "until": "2026-06-01", "failure": null, "limit": 50, "anomaly": true, "order": "desc" } } AxiosError: Network Error at push.m.onerror (https://explorer.ooni.org/_next/static/chunks/2s_s1862pp545.js:2:49148) at XMLHttpRequest.n (https://explorer.ooni.org/_next/static/chunks/0e1nv2rrn7z4k.js:3:4819) at tg.request (https://explorer.ooni.org/_next/static/chunks/2s_s1862pp545.js:2:60687) at async B (https://explorer.ooni.org/_next/static/chunks/1is9y5_ohz9-7.js:2:27311) at async https://explorer.ooni.org/_next/static/chunks/2s_s1862pp545.js:2:75957 When I check the developer console, I see that the request to https://api.ooni.org/api/v1/measurements?probe_cc=PL&domain=dn42.dev&test_na... until=2026-06-01&limit=50&anomaly=true&order=desc results in a 429 error (although this isn't visible in the screenshot). The API itself appears to return the error message "quota exceeded". There's no sign of that in the screenshot either. 1. Why am I already hitting the limit after just a few requests? 2. I have the following suggestion for the Explorer itself: Include the API error message - such as "quota exceeded" or 429 directly in the error message instead of just "meaningless" (-> AxiosError Network Error) JSON data.
