Re: [tor-relays] Accounting and the 'Stable' flag

I just want to make sure that... the ISP is not throttling traffic without notification.

Yeah, that's a valid concern. Aside from running through some of the M-LAB tests (https://www.measurementlab.net/tests/), it can be hard to predict or detect this.

Another issue that can crop up is poor peering capacity between your ISP and the rest of the Internet. In particular, in order to get a good consensus weight, the Tor bandwidth authorities need a good path to your relay. This can be really hard to measure. I have run into at least one provider that had great bandwidth when measured with nearby hosts or localized CDNs, but somewhere in the path to the bandwidth authorities there was congestion or some other issue preventing good connectivity.
