Storage slowdowns due to failing disks

Hey folks,

We’ve gone ahead and replaced some disks in your storage as the type of failures they are generating right now cause dramatic slowdowns in I/O performance for the disk arrays.

As a result of the replacements, the array will remain slow for a period of ~5 or so hours as the arrays rebuild themselves to have the appropriate redundancy.

We’ll be keeping an eye on this problem as we have recently noticed a spike in the number of these events as of late.
