I have had a look at the Festool international site (festool.com) and it looks as it has done for the last few years and very similar to the way the UK site used to look.
They're all being updated in a phased programme. The .DE site was first a few weeks ago.
It should make content far easier to access on all devices, mobile included, and will make content creation and upkeep significantly easier. If you have suggestions for improvement, or you are having problems accessing content that was previously available, please do let Festool know.
It's quite a task to make the sort of change they have, and it will benefit everyone in the long term. In the short term though, there are bound to be some teething issues, and I know not all content has been migrated yet and some links still take you to the "old" view.
