 | Some Turbulence |
You've probably noticed that the ride has been a bit bumpy on WP.com the past week with a widely covered DDoS attack last week and then another interruption a few hours ago from an unrelated network maintenance issue. Our core mission is enabling the world to publish, and anything that affects the availability of your site or dashboard impedes that.
Anything less than 100% availability drives us to work harder. Rest assured that behind-the-scenes here at Automattic we're learning as much as we can from these incidents so we're even better prepared and more able to adapt next time something unexpected comes our way. (We weather DDoS attacks every day on WP.com and 99.9% of them have no user impact.)
In a previous post I wrote about downtime I ended with the sentence, "For those following along at home, we're now powered by 152 physical processors, 511 gigabytes of memory (RAM), 174 hard disks with several terabytes of storage, and we're adding new servers constantly."
That last part about "adding new servers" was especially true, for WP.com we're now at 8,921 CPU cores across 2,475 physical processors, 8,200 gigabytes of memory (RAM). We've changed how we've done storage, but now that layer includes on its own 1.3 terabytes of RAM, 1.3 petabytes of storage, and 8.9 terabytes of solid state disks. (Plus Amazon S3, which we use as backup to our internal systems.) Also, we're adding new servers constantly. :)
Keep blogging, and we'll keep doing our best to make sure you never have to think or worry about this stuff.
