Opal14 (SFO shared hosting) is currently not responding. We're investigating at this time.
There was a second incident of the same type of problem but on a different site operated by the same customer. We've mitigated the problem to prevent it from occurring again and the server is stable at this time.
Opal14 is back online. The cause of the issue was high Apache RAM usage which resulted from a bad rewrite rule in a customer site. We've isolated the site and are working with the customer to correct the problem. We'll continue to monitor.
