This is actually a confirmed issue with regards to caching.
Our developers are still looking into this.
But with regards to your issue about the website loading to 3-4 minutes, that issue is on our customer's side and not on iClan Website's side, because we are not experiencing that issue when we are trying to replicate it.
If the servers would go down, we will get a notification but there are none currently.
Thank you again for using iClanWebsites!
