Maintenance page - hosted on LTM or redirect with fallback host - or both?
I'm in the process of implementing an automated maintenance page that is displayed when I have a pool with no healthy members. Looking around, I see two distinct methods of doing this - utilizing the fallback host feature and redirecting to another url, or setting up a page to be hosted on the LTM and using an iRule with "[active_members [LB::server pool]] < 1" in it.
Does anyone have any opinions on which one is preferred, and why?
Currently, I'm using the fallback host method and I'm redirecting to a page hosted on AWS.
My setup includes about 70 virtual servers on a 3600 HA cluster - some are QA, some are non-http. I will likley have the need for multiple versions of the maintenance page, depending on the site content it fronts.
The one thing I do see as an advantage of the LTM hosted option is that an iRule code example shows a refresh option being used to automatically pull up the healthy site when it becomes available.
Thanks!!
