Hi,
Those with secondary DNS service with BitFolk will have received a
number of alerts regarding
b.authns.bitfolk.com over the last couple
of hours.
The ISP concerned seems to be having some networking issues
that's affecting their IPv4 but not IPv6. I've reported the problems
to them and disabled alerting for that host until they fix it.
Cheers,
Andy
