acc.co.nz

acc.co.nz looks reachable from here — but still can't load it?

If Website Worth Up or Down says a site is up but it still won't open for you, the issue is usually on your end rather than the site's — start with these:

• Hard-refresh the page (Ctrl/Cmd + Shift + R) to rule out a stale cached version.
• Try the site in a private/incognito window — this rules out browser extensions and stored cookies as the cause.
• Flush your local DNS cache (on Windows: open Command Prompt and run ipconfig /flushdns).
• Try a different network — for example switch from Wi-Fi to mobile data — to check whether it's your ISP or router.
• If you're on a work or school network, the site may simply be blocked by a firewall or content filter.

If none of that helps and the site shows as “down” above, it's most likely an outage on their end — try again in a few minutes.

How this check works

When you load this page, Website Worth Up or Down makes a live connection to acc.co.nz and records exactly how it responds — the same request your own browser would make. Alongside the basic up/down result, we run a handful of supporting checks: DNS resolution, SSL certificate validity and expiry, domain registration status, and which ports respond, all shown in the cards above.
