Over the last two days, the Gawker Media sites measured by GrabPERF have shown significant degradation during peak hours.
Live data can be viewed here.
Most folks who read the affected blogs in feed readers will likely not notice the problem. However, no reason for the degradation has been released.
UPDATE: Gawker posted on the performance issue this afternoon [here]. Apparently there was a fermentation-related incident near one of the servers and specialist teams are working to resolve the issue — I hear they brought in these guys.
[NB: Beating a server does not make it go faster, Nick.]
