Apologies if you’ve experienced recent problems accessing the website

Apologies if you’ve experienced recent problems accessing the website:
we had a server issue which became impossible to fix without outside assistance.
[ Thank you Martin at Dataflame! ]

If anyone reading this is computer-literate enough to explain the circumstances that can lead to cpanel becoming out-of-memory to the extent that cpanel access itself becomes impossible, and whether it is possible for an externally hosted wordpress-based site to mitigate against a future re-occurrence of said circumstance, please email mark@sithean.com with the email subject title ‘server issue’ as your input would be most welcomed!
