You can switch your current TTL and reduce the time before you perform the migration. 600 (10 minutes) is a good TTL value, you must do it at least 24 hours before the migration. 10 minutes before making the change, you can set it even lower, to 60 (1 minute).Starting Price: Free -

Oh Dear is a fully featured app, with an API, webhook support, Slack/HipChat/Pushover/mail alerts & plenty more in the pipeline. Your DNS records are the crucial behind-the-scenes component nobody notices, until it's broken. It is what translates your domain name (what we humans understand) to an IP address (what computers understand). Oh Dear’s uses the full potential of each platform’s integrations so that notifications become smart and actionable: e.g. you can rerun the uptime check without ever leaving Slack. If the primary location reports an error to Oh Dear, the secondary location is used to verify the problem. We'll only trigger an alert if both the primary and the secondary checks report the site as down.Starting Price: $17 per month -
