Internet Speed Test

Internet speed test provided by Cloudflare

  • For testing the internet speed provided by your ISP: shows download/upload speed and Latency/Jitter
  • Uses Cloudflare data centers in more than 300 cities worldwide to test against the server closest to you
    • An Edge application running on Cloudflare Workers
    • Rather than finding the center by GeoLocation from the IP address, it finds the nearest center through network routing with BGP, which is much more accurate
    • Uses Cloudflare's Anycast Network
  • Cloudflare does not disclose actual data center locations, so they are shown near the closest airport on the map
  • There is also https://www.speedcheck.org/.

Bulk redirections

Define a large number of URL redirects at the account level using a given HTTP status code. Create Bulk Redirect Lists and reference them in Bulk Redirect Rules to set up millions of static redirects across all zones.

To find it in the dashboard, in the left sidebar go to 

보호 및 연결 > 제공 및 성능 > 대량 디리렉션

The URL is https://dash.cloudflare.com/<id>/bulk-redirects.

CSV Format

You can use a CSV file to import URL redirects into a Bulk Redirect List using the Cloudflare dashboard. Each line in the CSV file must follow this format: 

<SOURCE_URL>,<TARGET_URL>[,<STATUS_CODE>,<PRESERVE_QUERY_STRING>,<INCLUDE_SUBDOMAINS>,<SUBPATH_MATCHING>,<PRESERVE_PATH_SUFFIX>]

Example CSV file

All the lines in this example are valid lines that you can import in the dashboard: 

example.com/contacts,https://example.net/contact-us,301,,,,
example.com/about,https://example.net/about-us,,FALSE,TRUE,,
example.com/docs,https://example.com/draft-docs,302,,TRUE
