Where we have been able to identify that DNS is hosted externally we have sent an email to the technical contact listed on the account (as set in the notifications area of cPanel) with the new IP address.
We are also migrating our own marken.com.au and secure.marken.com.au sites in this batch.
Tweaking of mail scanning (spam/virus), firewall rules and general PHP / Light Speed configuration is being done on a per case basis.
Please contact us via hello@marken.com.au or
https://secure.marken.com.au/help/ if you have any questions.
