You're moving the goalpost way further or have a completely different goal in mind than I do. The only thing that you need if you want to publish content online is an nginx config and a machine with a public internet access. And that's it. No CMS, no wordpress. Almost nobody has a need for 100% uptime so I don't see why you would mention that. If someone wants to DDOS you you have completely different situation and it is very likely your content will be offline, which is fine, no? It's costing them money and the only downside on your side is to not have your publications available for some amount of time. If you're talking about business services, sure, that's a big deal, but for a person sharing their writing, that's a non-issue. It takes what, something like 30 minutes to get another machine, setup nginx, then upload your content?

A $5/month server with debian + nginx serving static content can survive way more than a HN hug of death.
