SPF hosted on CENT OS. Does not restarting the “named” service after editing the SPF record break the whole DNS File?

We had to change and Include entry from: Include:Domain-name.com to: Include:_Domain-name.com This was the only change we made. After a couple days none of our hosted resources were available.

updated SPF record using Include:_spf.domain-name.com formatting… seemed to break DNS file? Running on Linux

We were told to change it to Include:_spf.domain-name.com. This makes sense but upon doing so, after the records updated, none of our hosted…
