I thought I'd better say hello, even though there's not much to report at this stage today. I've spoken to our hosts again, and the net closes in on the hacker(s).
I'm hoping that we'll be back online at some point today, but it's obviously in the hands of our hosts, so I can't be 100% certain, as even with the best will in the world, IT projects rarely run to schedule. If the site comes up and is a bit wobbly, that'll basically be down to the hacker still trying to take down the server.
I'll try and update this later today if the site's still not up, but I have a hozzy appointment so might be a bit erratic in responding to emails etc.
Thanks for the messages of support etc. that have been trickling in... much appreciated. :o)
UPDATE: IT support have just confirmed that we should go live again today.
