Warhorn Downed By Expired Certificate
Warhorn, a popular platform for game signups and small gaming conventions, had an outage this past weekend due to an expired security certificate. Although the site itself was up and running, few browsers would allow users to reach it after detecting that the certificate had expired.
Not only were conventions using it in progress, the trouble started on Free RPG Day, when many groups using Warhorn had extra games scheduled, making the timing especially unfortunate.
The Organized Play Foundation, which took ownership of Warhorn last year, was quick to respond, filing a ticket with its hosting provider to renew the certificate, though loading problems persisted through Tuesday for some. At 19:01 Pacific Time (UTC-7), the OPF declared the problem fully fixed.
