opal15.opalstack.com (Frankfurt shared hosting) is currently not responding. We're investigating.
opal15 is back online. The cause of the outage was high server load driven by a compromised customer site. The site has been taken offline and the server is now operating normally. We'll work with the customer to prevent further disruption.
We've been unable to access the server to troubleshoot, so we've decided to reboot the server. The reboot is now in progress.
