Can we schedule a time for our pools to recycle daily?

Well pools are recycled daily and every 20 minutes if you have no traffic. However, to re-start the pools, unfortunately, at this point, a staff member needs to do it. However, the latest update to our control panel which is coming up soon will allow you to start/stop your own app pool from the control panel as well.

Why it doesn't restart automatically ?

It will attempt to do so, A 503 means that this attempt has failed due to some error with the site. A manual restart will override this, but if you are seeing 503's frequently, you should investigate the web logs to see what is causing the failure.

As noted in the article, this usually indicates something within your site has caused the application pool to crash. Contact any of our support personal and we can restart it for you.

503 errors generally stem from problems within your site. A coding problem or memory leak will consume all the resources in your pool until it crashes. At that point a restart of your application pool is required. If you can create a support ticket, we can look at your issue in details to see what specific problems it is having.

Problem is that each site doesnt seem to have its own aqpplication pool. I get this error on all my sites, which are on the same shared server. That makes me believe that the application pool is for each user with all his domains, or even worse, one application pool for the whole server, which have thousands of domains. Please verify how application pools are distributed and that they are configured correct. It seems that mine restart when they crash, but it happens very frequently, some times every 5 minutes

It depends on how you setup the websites. If you did not enable the recommended option for the sites to have their own application pools then they will all share the same pool for your account.
