Unable to open the documentation page (in Germany)

[Lexachoc]

I really don't know why the TanStack Query/Router/... documentation pages sometimes won't open (the tab just keeps showing “Loading...”).

I live in Germany and use Vodafone. Is the problem with this website's web hosting provider or with Vodafone?

This has really been driving me crazy these days. Usually, this lasts 5 to 10 minutes.

As I’m starting this discussion, the pages are now accessible again.

(This is my third attempt to start this discussion, and here it is....)

Sounds like the network path between Vodafone and the site, not the host. A temporary DNS or routing problem between your ISP and Cloudflare.

A few things to try:

1. Switch your DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8), on your OS or your router.
2. Install Cloudflare WARP (the 1.1.1.1 app). It routes you through Cloudflare directly.
3. Next time it hangs, open the same page on mobile data. If it loads there, the problem is the Vodafone line, not the site.

If it still hangs on a different network and a different DNS, then maybe a host issue.

@ryanportfolio thanks for the info!

I've already tried method 1 with the Google DNS servers (8.8.8.8/8.8.4.4) before, and it's really hard to say…

After using the Google DNS, the page still kept hanging. But after about 5 minutes, I gave up, removed the Google DNS addresses, and went back to the automatically assigned DNS server. Then the website just opened... (no idea why that worked...)

Maybe Cloudflare doesn’t like Vodafone. ( or vice versa lol)

I'll try using Cloudflare DNS (1.1.1.1) or Cloudflare Warp next time when it hangs again.

This looks like a client-side routing/DNS issue rather than hosting. The docs are served through Vercel's CDN, and a SPA stuck on "Loading..." usually means the JS chunks never arrive.

Next time it happens, try in this order:

1. Switch DNS to 1.1.1.1 or 8.8.8.8 — ISP DNS (Vodafone) can hand out stale or broken edge IPs.
2. Disable IPv6 in your adapter settings — intermittent hangs on German ISPs are a classic IPv6 routing symptom.
3. Open DevTools → Network and look which request is pending/failed — that shows exactly which domain is stuck.
4. Check status.vercel.com at the same moment. If it's green, the problem is on the path between you and the CDN, not the hosting.
5. Try a private window with extensions disabled — an adblocker can silently block a CDN script and the SPA spins forever.

If it affects only Vodafone and only for a few minutes at a time, it's most likely BGP/routing flaps on the ISP side — nothing the TanStack team can fix, but the steps above will tell you in two minutes which one it is.
