The mentioned problem turned out to be a bug in whois.nic.ch when
handling IPv6 requests. The bug only appears in rare events. We will of
course fix it.

Hello Benoît
I'm not sure at what time and from which IPv6 address you tried.
I just tried to find log entries with my co-workers operating
whois.nic.ch for 2001:4060:dead::/48 on the 26th Apr 2015 and found nothing.
If you want me to look into this, can you provide exact information?

Hello
Who else experiences that problem since a couple of days?
$ whois direktion.ch
The number of requests per client per time interval is
restricted. You have exceeded this limit.
Please wait a moment and try again.
(query was done via IPv6)
$ whois -h 130.59.31.241 direktion.ch
whois: This information is subject to an Acceptable Use Policy.

works!
I'm not doing more than max 10 queries/week from that specific ipv6 address,
probably much less.
I'm not aware of having other clients within my /48 network doing any
queries
to whois.nic.ch (yes, my blacklist scripts do a lot of queries to
whois.ripe.net and other RIR's to get abuse contacts, but not to switch)
