It's a cool project, but I'm not sure how huge that is.

If you have 5000 nodes running this, that could be as small as distributing 23.8 gigs/day to each node over the course of the month.

3.4PB/month is only 111,000 GB/day. That's not particularly huge in this day and age, except to consumers.

I imagine this traffic is fairly bursty as well.

Also keep in mind this is a data distribution system. In the case of large data pushes, new builds, etc. it's important that all peers get the new data on a timely and reliable manner.

I suspect you're underestimating the problem this project solves by focusing on a mostly irrelevant data rate stat.

> The reliability is up to 99.9999%

"up to"... Certainly looks like a wrong wording.

I read it in the "we have now gotten it up to X" sense, such as "I'm now up to my 5th beer"

except reliability reduces a total, not sum integers like beer count.

if I write a shell script with a scp line right now I can tell you it has 100% reliability. up to X% reliability means that "in the very nice and controlled environment, with the own devs attacking every production problem, trying to get 100% got us up to X%"

Except that is clearly not what they where trying to communicate.

That's the way to read it.
