Back in business!
Yesterday from about noon to 4pm the server which hosts this website (and many others) was down. This unfortunately lead to an interruption for which I apologize.1 During this time I was unable to send/receive emails and the website was unavailable.
The hosting company I use is very good. When there’s been downtime it normally occurs during non-peak hours and is very short in duration. This was an anomaly.
Anyhow, everything is back on line and open for business.
