Hello, over the past week, I've observed issues resolving resources under the hpe.com domain. It follows the same pattern; in the AM, we cannot access anything and get an NXDOMAIN message. Around 2pm EST, it clears up and everything works until the next day.
My internal DNS team reports that hpe's DNS servers become inaccessible throughout the day, and our server can't resolve it. We've opened a tac case but claim that nothing is wrong. When we switch to a public DNS provider, we're able to resolve without issue (most likely cached long enough so we don't see an issue).
Reaching out to the community to see if others might be having the same problem, or if I need to continue to hunt internally.
tia,
