Dear bandwidth authority operators,

However, judging from its web server logs, several systems on the internet are pulling bwauth files form siv. If you are running one of these systems, please let me know how badly you need to continue doing this and for how long.
If you can, please use different servers for your bandwidth files.
If multiple operators are using the same server, then it becomes a single point of failure for the bandwidth measurement system.
Similarly, try not to use servers that depend on torproject.org, because then the tor project DNS becomes a single point of failure.
Thanks for your hard work!
So what's the best choice here? I don't think I have the capacity (neither speed or bandwidth cap) to self-host this on ritter.vg. I can use https://www.seul.org/ like moria. Or I can use fastly. Or something else?
If no-one can run a server, I think your best option is to use fastly and seul.org. (Torflow can download from multiple servers.)
Here's my analysis:
seul.org: + doesn't depend on torproject.org DNS ? shared with moria1, might cause bias or bandwidth issues - shared with moria1, reducing redundancy
Fastly: + built-in redundancy ? does it depend on torproject.org DNS? ? CDN servers near exits might cause bias
Both: + built-in redundancy + doesn't depend on torproject.org DNS ? some potential bias, but not as much as a single server
