# Will content resolution hold up during Black Friday traffic, and what if it times out?

Asked by Ravi Chandran on 2026-07-09. Tags: shopify, hydrogen, performance, black-friday.

Preparing a Hydrogen store for Black Friday. Last year a client-side testing
script fell over under load and blanked our hero for a chunk of the morning.
Not repeating that.

Two questions, failure modes only please, no marketing:

1. Content resolution latency under spike. Published numbers?
2. Exact behavior when a content request times out mid-request. What renders,
   what does the visitor see, what do I control?

Taking your two questions in order.

1. The documented figure is end-to-end response times under 90 milliseconds
at P95. Since the fetch happens in your loader during SSR, it is not on the
client's critical path at all.

2. Timeout behavior is in your hands via the [loader pattern](https://docs.croct.com/reference/sdk/hydrogen/content-rendering). You include
[fallback content](https://docs.croct.com/explanation/content/fallback-content), and a timeout serves the default content instead of
breaking the page:

```ts
const {content} = await context.croct.fetchContent('home-hero', {
    fallback: defaultHeroContent,
});
```

So the worst case for a visitor is the default hero, never a blank one. The
page renders either way.

The timeout itself is configurable through `defaultFetchTimeout` on the plug
options, so you decide the latency budget: set it tight and a slow response
degrades to the default sooner rather than holding the loader.

For your preparation: pick the timeout that fits your SSR budget, load
test with the fallback path forced, and confirm the default hero is one you
are happy to show at peak.

Ran last Black Friday on this exact stack. One operational note to add: make
your fallback content seasonal too. Our default hero was the evergreen brand
one, so the handful of timed-out requests during the morning spike showed a
non-sale hero to those visitors. Cosmetic, but the merch team noticed. This
year the fallback is the sale hero itself.
