Title: HN went down for nearly all of Monday the 6th. I suspected failing hardware.<p>I configured a new machine that is nearly identical to the old one, but using ZFS instead of UFS. This machine can tolerate the loss of up to two disks. I switched over to it early morning on the 16th, around 1AM PST.<p>Performance wasn&#x27;t great. Timeouts were pretty frequent. I looked into it quickly, couldn&#x27;t see anything obvious, and decided to sleep on it. I switched back to the old server, expecting to call it a night.<p>Then the old server went down. Again. The filesystem was corrupted. Again. So I switched back to the new server. During this switch some data was lost, but hopefully no more than an hour.<p>And here we are. I&#x27;m sorry that performance is poor, but we&#x27;re up. I&#x27;ll work to speed things up as soon as I can, and I&#x27;ll provide a better write-up once things are over. I&#x27;m also really sorry for the data loss, both on the 6th and today.
