Pageflakes may be up again but there are questions about its long term viability. Phil Bradley’s blog posting Pageflakes is dead, or is it? may encourage you to think of moving your start page elsewhere. I moved UKeiG’s Pageflakes ‘stuff’ to Netvibes after the advertisement fiasco (see UKeiG Pageflakes content has moved to Netvibes). As well as the lack of advance notice of adding adverts to pages – later withdrawn after many vociferous protests – there had been technical problems, slow page loading, and repeated down time. We felt that we could no longer trust Pageflakes nor could we depend on them to provide a reliable service.
At the very least I would recommend that you document your Pageflakes content. In the longer term, consider moving to Netvibes or a similar service. Phil Bradley has a list of start pages at http://philbradley.typepad.com/i_want_to/create_a_personalised_start_page/
