Data & methodology

Every colored pixel on the map means something. Here’s exactly what, and where it comes from.

The speed layer

The base layer is built from Ookla® Open Data: aggregated, anonymized results of real Speedtest® measurements worldwide, published quarterly as ~600 m map tiles. We aggregate those tiles into the grid you see, weighting by the number of tests in each tile. “Wi-Fi” shows fixed-broadband results (the lines hotels, homes, and cafés run their Wi-Fi on); “Cellular” shows mobile-network results.

Current data period: Q1 2026. Speedtest® by Ookla® Global Fixed and Mobile Network Performance Maps was accessed on 4 July 2026 from AWS and used under the CC BY-NC-SA 4.0 license. Ookla trademarks used under license and reprinted with permission. Some regions are absent from the source dataset; blank areas can mean no data rather than no internet.

The verdicts

Rather than make you interpret megabits, we translate the typical download speed (adjusted for latency) into five plain-language bands :

• Rough · Expect a struggle. Plan offline backups.
• Spotty · Messaging works. Meetings are a gamble.
• Workable · Email and browsing are fine. Video calls can wobble.
• Solid · Video calls and streaming should be fine.
• Excellent · As good as home. Call, stream, upload away.

Thresholds are stricter for Wi-Fi than cellular, since a fixed line is usually shared harder. Very high latency knocks a verdict down a band; a fast link that lags still feels rough on a call.

Traveler reports

Two kinds, both anonymous. Ratings: the five-segment bar, one tap from rough to excellent, optionally tagged Wi-Fi or cellular and with your carrier. Speed tests: run from the site itself against M-Lab, the open measurement platform used by researchers and regulators worldwide. Reports show up on the map immediately and matter most exactly where the big dataset is thin: that one hotel, that one beach town.

Honest limits

• Area averages are averages. A hotel can run slow Wi-Fi in a fast neighborhood, and one great café can’t fix a slow one.
• Carrier-specific roaming performance has no public dataset anywhere; traveler reports are the best signal.
• Sparse areas rest on few tests. We always show the sample size; read “3 tests” with the grain of salt it deserves.
