Massive increase of SERVFAIL after April 28th 2025.

[vincent at cojot.name]

Hi Rob,

Unfortunately, as soon as I remove the 'forwarders' in any of my named 
servers, the problem comes back. The output in my previous message was 
captured just a few minutes ago after I had disabled 'forwaders' in one of 
my bind servers.

Regards,

Vincent
