I apologize for the 9-hour downtime yesterday, April 18. Apparently it was caused by the incorrect SSL usage. A new certificate was issued, which fixed the issue.
May want to setup a free monitor at uptimerobot.com. You can setup an HTTPS check and have it look for the word "enthusiasts" since that's in the footer. If it finds it, it considers the forum up. If it doesn't, then it would send an alert. You can get up to 50 free ones every month.
