I'll comment about my previous message:
https://lists.torproject.org/pipermail/tor-talk/2016-March/040677.html

Recently admin of that service decided to shut it down. He told about
personal reasons like moving to another place where he will be unable to
get stable internet connection to manage his service. Users wrote that
two hours later after this announcement service went down. Onion
service disappeared permanently.

I was right. Check new metrics link:
https://metrics.torproject.org/hidserv-rend-relayed-cells.html?start=2012-12-26&end=2016-04-25
At the end of March when service went down speed drastically dropped from
1500 MB/s to about 700 MB/s. So, the single onion site consumed 800 MB/s.
