Why are videos buffering or not playing properly on Ten Ten?
Overview
If videos are loading slowly, buffering, or becoming unwatchable, this is usually due to school network settings or bandwidth restrictions, rather than an issue with the Ten Ten platform itself.
Why does buffering happen?
From what you’ve described, this is most commonly related to:
- Network filtering or firewall restrictions
- Insufficient bandwidth on the school network
- Blocked access to video hosting services
All Ten Ten videos (including Life to the Full and CPD content) are hosted via Vimeo, so smooth playback depends on your network allowing these connections.
What is the most important thing to check?
The key step is to ensure that the correct domains are whitelisted on your school network.
We recommend asking your IT team to allow full access to the following:
- *.vimeo.com
- *.vimeocdn.com
- *.akamaized.net
- *.appspot.com
- *.googleapis.com
- *.google-analytics.com
- *.hopx.cedexis.com
If any of these are restricted, it can result in:
- Videos starting but not playing smoothly
- Constant buffering
- Playback stopping altogether
Where can I find technical guidance?

Are there other things to check?
If whitelisting is already in place, you may also wish to check:
- Internet speed and bandwidth during lesson times
- Whether multiple devices are streaming simultaneously
- Browser compatibility or updates
Summary
- Buffering is usually caused by network restrictions or bandwidth
- Ten Ten videos are hosted via Vimeo
- Ensuring the correct domains are whitelisted is essential
- This typically resolves playback issues quickly
