Large Post-quantum Keys Slow Virtual Private Network Handshakes, Tests Show - Quantum Zeitgeist
Quantum Zeitgeist is reporting on the story above. It caught our attention because it may affect readers checking their internet or a specific service on SpeedTestTools right now.
When you turn on a VPN, your device and the server must introduce themselves and exchange security information before you can start browsing. Upgrades meant to protect against future advanced computers use much heavier digital keys, which slows down that initial greeting. For regular users, this means the wait between pressing connect and actually being online can take noticeably longer than usual.
If your VPN feels sluggish when starting up, you might already be testing these newer safeguards. Take a look in your VPN app settings under connection type or security features. If you are experiencing long startup delays or connection timeouts, you can often test a standard connection method to see if things speed back up, or make sure your app is fully updated with the latest software fixes.
Stronger future privacy sometimes brings small delays today. Give your app an extra moment to complete its setup before assuming your internet has stopped working.
- Run a quick speed test — get concrete numbers before assuming it's your ISP.
- Open the Down Detector board to see which major services are actually having issues right now.
- If numbers look off, walk through the Fix-My-Internet checklist — most issues clear in the first two steps.
