From our web hosting centre status page about 45 minutes ago:
During a planned maintenance something went wrong and many servers/services became unavailable over the network. Our network team is investigating the issue currently.
I switched our domain to point to a server which would give members a message rather than leave them hanging .. but the problem was fixed before the updated message was on that server.
Result - you MAY an odd page "Well House Consultants back server" come up ... and caching means that may happen for up to 48 hours ... but all looks like its back properly.
