Hi Dave,

well, it was a free service and it lasted a long time. I want to raise a toast to Justin and convey my sincere thanks for years of investing into the "good" of the internet.

Now, the question is which test is going to be the rightful successor?

Short of running netperf/irtt/iper2/iperf3 on a hosted server, I see lots of potential but none of the tests are really there yet (grievances in now particular order):

OOKLA: speedtest.net.
        Pros: ubiquitious, allows selection of single flow versus multi-flow test, allows server selection
        Cons: only IPv4, only static unloaded RTT measurement, no control over measurement duration
        BUFFERBLOAT verdict: incomplete, maybe usable as load generator


NETFLIX: fast.com.
        Pros: allows selection of upload testing, supposedly decent back-end, duration configurable
                allows unloaded, loaded download and loaded upload RTT measurements (but reports sinlge numbers for loaded and unloaded RTT, that are not the max)
        Cons: RTT report as two numbers one for the loaded and one for unloaded RTT, time-course of RTTs missing
        BUFFERBLOAT verdict: incomplete, but oh, so close...


NPERF: nperf.com
        Pros: allows server selection, RTT measurement and report as time course, also reports average rates and static RTT/jitter for Up- and Download
        Cons: RTT measurement for unloaded only, reported RTT static only , no control over measurement duration
        BUFFERBLOAT verdict: incomplete,


THINKBROADBAND: www.thinkbroadband.com/speedtest
        Pros: IPv6, reports coarse RTT time courses for all three measurement phases
        Cons: only static unloaded RTT report in final results, time courses only visible immediately after testing, no control over measurement duration
        BUFFERBLOAT verdict: a bit coarse, might work for users within a reasonable distance to the UK for acute de-bloating sessions (history reporting is bad though)


honorable mentioning:
        BREITBANDMESSUNG: breitbandmessung.de
        Pros: query of contracted internet access speed before measurement, with a scheduler that will only start a test when the backend has sufficient capacity to saturate the user-supplied contracted rates, IPv6 (happy-eyeballs)
        Cons: only static unloaded RTT measurement, no control over measurement duration
        BUFFERBLOAT verdict: unsuitable, exceot as load generator, but the bandwidth reservation feature is quite nice.

Best Regards
        Sebastian
