I want it to do something when stuff doesn't work. Replacing one thing with another might improve the situation (or not) but the real problem is failure imho.

I want it to do something when stuff doesn't work. Replacing one thing with another might improve the situation (or not) but the real problem is failure imho. To needlessly ramble on a bit: A simple header or html tag could "ok" all or specific alternative ways of distributing and provide conditions. Say, if my blog is unavailable for > 3 months you can p2p distribute it by [for example] fast, medium or supper slow means. Currently I look at articles I wrote long ago. I've carefully selected 10-30 links of which 20% still work(!?) I've picked them specifically because they are probably unfamiliar to those interested in the topic.
