A few new red dots have appeared on the GridPP status map. I suspect some of you may not have renewed or replaced host or gatekeeper certificates which expired on 30 October or later. I believe Andrew sent out reminders for all expiries but they would have gone to the same place as the original cert which may be a machine where you don't normally read mail. Can you all check the colour of your dots on http://ukmap.gridpp.ac.uk:8001/ and take action. Thanks, John
