Just recently I noticed that my Shopify store is broken whenever I’m connected to my WiFi and work and at home. I attempted to check other Shopify stores and I noticed that a lot of stores I’ve used in the past are also broken whenever I’m on my WiFi. I attempted to have other co-workers check my store as well, and they were also not able to see the website like they should normally. I tried different internet browsers but experience the same issue. Why am I experiencing this problem only in Shopify based stores? It’s almost like I’ve been IP banned at my home and work WiFi locations.
Looks like all resources ( images, js, css files, etc ) are blocked. You can try to ping cdn.shopify.com.
1. Open Command Prompt
2. Type in "ping cdn.shopify.com" then press enter
1. Open Terminal
2. Type in "ping cdn.shopify.com", press enter
3. After it does a couple of tests, you can stop it by Ctrl + C
Look at the results, you probably have 100% losses ( or more than 0% loss). If you do, one thing you can try is to change the DNS server to 184.108.40.206 and/or 220.127.116.11. Try to change the DNS on your iPhone first, while connected to Wifi. If that works, then change the DNS on your router. Your current DNS server ( your ISP by default ) is probably experiencing some technical difficulties right now.
