I use gmail as my mailbox. In the past 24 hours gmail has dropped from view with a 502 message (not just a regional problem it seems). If you have emailed me recently – the last 18 hours or so – I may not have seen your message. Emailing me at firstname.lastname@example.org – as per the contact info in the left hand column – will still find me.
Update: Sorted for the time being 2:39 PM.
