Solved: Notion not working!!!

Source: Dev.to

Executive Summary

Notion appearing offline is often caused by an outdated local DNS cache on your computer, not a service outage. Flushing the DNS cache forces the system to retrieve the current IP addresses for Notion. For persistent problems, consider switching to reliable public DNS providers such as Cloudflare (1.1.1.1) or Google (8.8.8.8).

Why DNS Cache Can Make Notion Seem Down

When you type notion.so into your browser, your computer queries a DNS server (the internet’s phone book) for the IP address. To speed up future lookups, the answer is cached locally on your machine and sometimes on your router.

If Notion updates its IP addresses—for maintenance, load‑balancing, etc.—your cached entry may point to an old address. Your computer then tries to connect to a location that no longer serves Notion, giving the impression that the service is down.

Solution 1 – Flush the DNS Cache

Windows

ipconfig /flushdns

1. Open Command Prompt as an Administrator.
2. Run the command above.
3. Quit and restart your browser (e.g., Alt+F4 then reopen) to clear any browser‑level DNS cache.

macOS

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

1. Open Terminal.
2. Enter the command and provide your password when prompted.
3. Quit and restart your browser (Cmd+Q then reopen).

Solution 2 – Use a Public DNS Provider

If your ISP’s DNS servers are slow or unreliable, switching to a public DNS service can improve resolution speed and reliability for all sites, including Notion.

Configure the DNS addresses in your system’s network settings or, preferably, in your router’s settings to apply the change network‑wide.

Solution 3 – Edit the Hosts File (Last‑Resort)

Warning: IP addresses can change. Use this only temporarily and remember to remove the entry later.

The hosts file overrides DNS lookups. You can map Notion’s current IP manually.

1. Find the current IP address:

   nslookup www.notion.so

2. Add a line to the hosts file with the returned IP (example shown):

   104.18.23.204   www.notion.so

3. File locations:

   • Windows: C:\Windows\System32\drivers\etc\hosts
   • macOS / Linux: /etc/hosts

Conclusion

When a service like Notion seems down only for you, the culprit is often a stale DNS cache. Flushing the cache, switching to a reliable public DNS provider, or—if absolutely necessary—editing the hosts file will usually restore access quickly.

Take a breath, open a terminal, and give your DNS a fresh start. You’ll likely be back in business before anyone else notices.
