GTM failure causing customer impact
We are kind of paranoid and thinking what if we have to keep the GTM down for several hours, then what will be our fallback. We already have redundant GTM but still we are exploring the question in case something happens to both GTMs.
Obvious option is to push out DNS change to point the IP directly to the LTM, but that will happen only after the fact. Is there any other option like for eg: Can we setup a DNS servers with IPs and define a failback something like
GTM A, GTM B, DNS C
So if if no response from GTM A, B then use C. And C can have IPs pointing to the LTM Is that possible?
Any other option?
