The story
When the flood appeal email went out to eleven thousand supporters, Grace’s small relief nonprofit got a year of traffic in an afternoon — on the cheapest shared hosting a grant would cover. The donation page crawled at precisely the moment generosity peaks and patience doesn’t.
Nonprofits run on volunteer webmasters and zero budget; “upgrade your server” isn’t advice, it’s a donation ask in the wrong direction. Static caching is the honest fix: the appeal page doesn’t change per visitor, so no visitor should cost a PHP request.
The free tier of xSpeed Cache covers all of it — page cache, prewarming, image conversion. The next appeal, the site held, and the only thing that spiked was the total.
