• Why does my blog HTTP 503 Service Unavailable when I click around using Firefox on iPhone?

  After migrating my blog to a new host, I noticed my website would crawl to a halt while I clicked around. I would see hangs ranging from 4 seconds to 15 seconds. If I click enough, I’d eventually see HTTP 503 Service Unavailable. Why was visiting my website causing it to hang? Here’s my debugging story.

I love doing things the “right way” and “the hard way” to learn and I hope this might educate or be a good reference in the future. I aimed to do my migration with no downtime, but my website did go down for a few minutes. For that, I explained what I did wrong and what I believe is the better method.
