Quick tips

Website down, Wi‑Fi issues, or slow loading?

A site can seem down on your side even when it is working for most people. DNS cache, ISP routing, firewalls, or a local network issue are common reasons.
If it works on mobile data but not on Wi‑Fi, the website is probably fine. The problem is more likely your router, DNS, or internet provider.
Slow does not always mean down. A site may still be reachable while dealing with heavy traffic, a bad deploy, CDN trouble, or regional congestion.
