Loading Issues

Having trouble loading a Stack? We have compiled the most common things to check below.

In rare instances where new content is being submitted for a Stack (via a CMS update) a small window may exist where the Stack is inaccessible for several moments until that new content has been fully submitted. In these instances, simply waiting a few moments, and refreshing your browser, will resolve the issue.

Is your internet connection stable? If you have a poor signal on a Wi-Fi network, and drop outs are experienced, this may affect your ability to load a Stack in full.

If your internet has minimal bandwidth, and load times are unusually long (e.g. 5 minutes or more), you may experience server drop outs.

Any reasonable ADSL or greater, or 4G signal or greater (with 3+ bars of signal strength) should be sufficient to load a Stack.

For more in-depth internet speed checking, please provide your results from https://www.speedtest.net/ to Inspace Support.

See Support Matrices for specific bandwidth benchmarks we recommend.

See Support Matrices for our specific web browser matrices.

Also to check specifically in this regard is whether the browser being used has WebGL 2+ and/or hardware acceleration enabled. See below.

Debugging whether hardware acceleration is being used can be determined via the Stack Debugger subdomain for any live Stack (e.g.: Inspace Stack).

To verify hardware acceleration is enabled, the machine has to check these 2 things:

Any modern smartphone or PC/laptop from the year 2015 onwards will be sufficient to render an average Stack as a minimum. For PCs and laptops, a video card with at least 1GB worth of VRAM is the minimum recommended specification.

Sometimes the assets themselves we provide may not be sufficiently optimised, and will incur poor performance regardless of hardware and internet connection.

For real-time rendered 3D assets, see: WebGL 1/2 Geometry Guidelines & Support Matrices

iOS at present also have their own suite of strict thresholds compared to Android.

Generally we recommend performing a https://www.speedtest.net/ from the device which your experiencing poor download times.

We can then compare your numbers with ours to get a good gauge on whether your bandwidth simply isn't sufficient for effective load times, or whether other factors are at play, to which we may consider:
