There may be some small downtime over the next 48 hours to allow my host to upgrade the server. It's possible that you may lose service for an hour or two.

Update 21 June: My hosting company is now rejecting all subscriber emails as spam. I'm trying to fix this as soon as possible. In the meantime, the RSS and maps are still working OK.

Update 22nd June: The problem is caused by the 'robot' email being lost. I've temporarily set the 'from' address on emails to 'dave' at notaminfo.com, which seems to have fixed the problem. I will revert to 'robot' as soon as my hosts fix the underlying problem.

Update 23rd June. Latest problem is that my hosts were severely limiting the number of emails I can send per hour. So some of you who get emails between 6 and 8am may have not had them sent out. This is now apparently fixed. Normal service is resumed!
