Yesterday/today’s downtime was due to server downtime, according to my host Asura Hosting:
We apologize for the inconvenience. We experienced a temporary server downtime. Our technicians are working on it to get it fully normalized again. The issue will be resolved shortly. We truly appreciate your patience in the meantime.
Do let us know if you have any other queries or concerns.
I reported my problem a few hours ago, and now the issue appears to be fixed and the sites are loading again.
