Hi All,
I'm having performance issues on my OpenVZ VPS. The provider has offered to move me to a new node that isn't congested. This requires an IP change and I am concerned for downtime due to DNS updates.
From my understanding of DNS I can prepare myself for the change by reducing the current TTL of my websites to a few minutes, wait for the current TTL to expire and then ask my provider to make the node/IP change. I think I am right in saying the only downtime then would be the 10 minutes or so it takes the provider to do the migration, plus the few minutes of DNS updates.
Is that right?
