Can you improve your DNS management system. Updating DNS from other providers like Godaddy is way better than your DNS system like you don't have to wait longer just to get your DNS updated. Is there a way you can improve it to make DNS update faster than waiting 4-8 hours before it gets updated? like right now I am updating the MX records by adding new MX records and removing the old MX records. The new record was updated in 15 minutes but the old records were not removed until like 8 hours. We can't wait that long if we are running a business.
