Onionoo bandwidth (issue ?)

Since we have set up a new server we see a 2 Mbps bandwidth limitation while querying https://onionoo.torproject.org/details?running=true

While with the previous server we have always a bandwidth > 10 Mbps

Both servers are hosted by the same company which can not explain the difference.

Would it be possible to have a traceroute from yatei.torproject.org to 213.246.53.127 (previous server) and 213.246.63.20 (new server)?
