The site has been up and down like a yo-yo. Dirk has been troubleshooting it for hours today and indications pointed to potentially faulty RAM on the new server. Within 30 minutes of submitting a ticket, the new host swapped out the RAM. Diagnostics now are looking much better.
Please note that the site might have to go on and offline without notice.
Also, Dirk will turn off the indexing (which is resource intensive) for the short term. This might be for a day or two and means site-wide searching will be inactive, but all members can read and write posts and access all other functions.
