We have a site that was in maintenance mode yesterday. So the start-page redirected to a "offline.html"-page.
Today we load the page again and IE is redirecting to offline.html and showing maintenance-site, though the page is online.
Other browser shows the site correct.
We deleted cache and refreshed dns-cache without any improvement.
Normaly we would reload the site with STRG-F5 but we can't, because after entering the main-page we are directed to offline.html at once.
And reloading offline.html wouldn't help.
How do we solve this problem?
