Live Mesh

Here, There, Everywhere...

  • Live Mesh

    The potential of Live Mesh is limitless...


    …but today’s implementation is not ;)  Our underlying platform is designed to enable a wide range of scenarios, at broad Internet scale. We closely watch the feedback from our Technology Preview users along with the health and performance of the service, using it to continually improve the system and ramp up our scale.

    As we go through this process, we’re hearing your questions about how many folders and files users can put in Live Mesh today. Here’s a quick summary of the upper bounds we’re testing against ourselves at the moment – we’ll expect these numbers to keep going up with subsequent service updates. [UPDATE: these are not limits that are hard coded into the system.  They are boundary guidelines we've established based on internal and external feedback, and we're confident that anything under these boundaries will work well for all users.  Because they are not hard coded limits, you can exceed these boundaries, and at that point your mileage may vary.  Feel free to certify and share your own success stories...and stay tuned as we will definitely increase these boundaries/guidelines as we complete further tuning and testing.]

    • Size we've currently tested for contents in a single Live Folder: 10GB 17GB 40GB (go Mesh test team go!) (of course there’s still the 5GB quota which limits how much you can synchronize with the Live Desktop)
    • Individual file size: 2GB
    • Items (file or folders) per Live Folder: 100,000
    • Members per Live Folder: 200
    • Number of Live Folders per user: 200
    • Number of devices per user: 100

    Live Mesh Expansion


    Amit Mital here – I run the Live Mesh & Developer Platform team. At Web 2.0 in April we announced Live Mesh and opened it up for people to try out our platform experience -- the first evidence of what scenarios our platform is capable of enabling.

    We said we’d tell you more about Live Mesh and give you access to the platform in the future, allowing you to build your own experiences on top of Live Mesh.  En route to opening up the developer platform we’ve been systematically updating and expanding the tech preview to help us scale out the underlying technology (see behind the mesh). We’ve enjoyed watching our service handling the load, and we want more!

    Today we are again increasing the number of available slots in the Live Mesh Technology Preview, and expanding the list of countries that will allow sign-up without a wait list to include Canada, India and Ireland! (although you still need to run with an English locale for now.) This is in addition to the availability we’ve previously announced for USA, UK, Australia and New Zealand (see coverage map).

    The experience you see today is just tip of the iceberg!  To see what the Live Mesh platform is capable of, check out the Channel 9 videos, and try out the user experience.  We’re eager for you help to keep pushing our scale, and your feedback!

    We do still have a maximum limit on the number of users we’ll allow into the Technology Preview, but as long as we’re below the limit, anyone in the countries above can sign-up today with no delays or wait list.

    Service update: new build coming today (0.9.3103.13)


    We are pleased to announce that our next update will be available later today is now available. The new build contains a number of reliability and performance improvements; we've highlighted the key fixes below. By default your Live Mesh software will automatically update itself within 24 hours of the new build being posted, but you can always right-click the Notifier icon in the system tray and choose to force an immediate update.


    • Increased the reliability of Live Mesh folder behavior in Windows Explorer.
    • Fixed a problem with the ‘Save As’ dialog in Internet Explorer when downloading video files from the Live Desktop.
    • Enabled syncing of files greater than 2GB in size.
    • Greatly increased the speed of P2P synchronization.
    • Implemented a number of reliability fixes for backend services.
    • And, of course, a bunch of additional general performance improvements.

    Windows Vista User Account Control (UAC) reminder

    While we no longer require that UAC be enabled when running Live Mesh on Vista SP1, if you initially installed Live Mesh with UAC enabled, and then disabled it, you might have some issues upgrading. Please see the “NOTICE: Updating Live Mesh and User Account Control (UAC)” Announcement on the Live Mesh forums for further information.

    And as always, thank you for all the great feedback!
