it’s getting even more complicated:
if I hardcode the ip-addresses of wordpress.com/ww.wp.xz.cn and the akismet-server in the /etc/hosts, then it works again. But:
The dns-queries from the working config (without an ipv6-address) and the non-working config (with ipv6-address) look the same:
from tcpdump (first line is the query, second line the response)
working:
11469+ A? rest.akismet.com. (34)
11469 q: A? rest.akismet.com. 4/0/0 rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com (98)
not working:
5152+ A? rest.akismet.com. (34)
5152 q: A? rest.akismet.com. 4/0/0 rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com, rest.akismet.com. A akismet.com (98)
Forgot one thing:
In the overview, where the entries from the WordPress Development Blog should be, there is only the following error-message:
RSS Error: A feed could not be found at http://ww.wp.xz.cn/development/feed/
(this is only one line)
