Hi Torproject,
as far as i can see my relay currently can advertise 560 KiB/s. That are 573,44 KB/s. 43C7BC2E17FB26B204EC0BD9AA784E4736979087
Following your dir-specs it should get the "Fast" flag if it can provide more than 100KB/s. https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n2595
At my other relay i already saw it providing 562 KiB/s and it got the "Fast" flag. A9DB853547A6459AB5190E62BF2F7B8F068FEB0A
It seems the limit is above 560 KiB/s? If i remember it right then i already read somewhere that the requirements are now higher than 100 KB/s so i guess your documentation is wrong? Am i missing something why my relay with 560 KiB/s dont get the "Fast" flag?

The default value for AuthDirFastGuarantee is still 100 KB. I don't know if a majority of authority operators have set it higher.
The other way a relay gets Fast is if it is in the fastest 7/8ths of the routers.

6/9 authorities use measured bandwidth, rather than reported bandwidth. So your relay won't get Fast unless it is measured by the bandwidth authorities, faster than 100 KB.

Right, it's this last part that's critical here. Directory authorities that do their own "bandwidth authority" measurements use their bwauth numbers rather than the self-reported numbers in the relay descriptor, for deciding whether to assign flags.
If you go to the very bottom of https://consensus-health.torproject.org/#relayinfo and put in this relay nickname or fingerprint, you'll see that 4 directory authorities -- the ones not running bandwidth authorities -- look at the self-reported number, and give the relay the Fast flag. But 5 of them, which are running bwauths, use their own numbers, which put the relay below the threshold. And since 5 is a majority of 9, their choice wins.
Hope that makes sense, --Roger
Yep makes sense now. Thanks for clearing this Roger:)
