It's not just PPRuNE, it happens with many other websites as well. Happens on my home computer, work computer, friends' computers etc. - all different 'net connections (both Cat 5 and WiFi). Have seen it a LOT over the past few weeks. Pages not loading properly (or failing to load completely), error messages etc. The whole kit and caboodle. Very frustrating.May try a different browser e.g. F'Fox.Smithy
