For the past few days we’ve been experiencing intermittent performance issues on server walnut. We’re evaluating our resource usage and traffic patterns to determine if this is just a phase or if we need to upgrade the server. We’ll update this post when we know more.
Update—22:35 PST: We’ve determined the traffic spikes to have been caused by botnets attempting to inject spam into blog comment scripts. The exploits failed because the comment scripts in question have secure antispam features, but the hits still consumed large amounts of server resources. We will be implementing filters to block this kind of traffic as soon as we can determine it is safe to do so.
