yesterday my server went inactive without any hints because of too less score. 
It ran without problems for over a year.
Does anybody else has the same problem?
Additionally the site loads very slow:

I checked ntp and it runs as usual

Looks like packets are being dropped somewhere between here and there.  Can you 
show a (ipv6) traceroute to www.pool.ntp.org?

This is from 2001:4b98:dc0:41:216:3eff:feac:1bc9 (at Gandi).

Both Jörg and Richard have their servers at OVH. I have one server there as well (not in pool though) and it shows similar results.

My IPv6-enabled server here in Finland can reach www.pool.ntp.org just fine. Here's its traceroute6 for reference:
