Github Map preview of TopoJSON is broken for me, GeoJSON okay.

Hello,

I noticed that over the past few weeks I have been having more and more trouble with getting TopoJSON GitHub previews to load, where they previously loaded fine. At first, my friend reported this problem in Canada, but I could not reproduce it. Now I myself am affected. Both Chrome and Firefox display this behavior for me. I’m curious if others are noticing it too.

Showing a TopoJSON file in a public repository: the error in browser map and in Chrome devtools.

Here is an example on a public repository: https://github.com/thadk/GeoTZ/blob/master/TZA_adm2.topojson

Showing a still-functional geojson file in a public repository: the same file loads okay (200)

This GeoJSON file is still working great: https://github.com/thadk/GeoTZ/blob/master/TZA_adm1_mkoaTZ.geojson

This seems to affect all my repositories at least: the main place I need it is in a particular private one where I depend on this as a quick method of collaboration. Thanks for the help.

This was the document that launched TopoJSON:

Here is someone else’s TopoJSON that is stuck (at least for me): https://github.com/jazzido/d3micromaps/blob/master/argentina.json

If someone else can just confirm they also see this issue on these two files, that would be validating.

Thanks and have a good weekend.

I didn’t notice as I had email filters, but I actually got this response! Thanks.
