[paularthur]

Hi,
https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.34/moment-timezone-with-data.min.js
is returning a 404. We use it for the ttnmapper-website app, which is currently broken.
Thanks,

[MattIPv4]

👋 I've escalated this internally. Is this a new issue you're seeing, or has this file always been missing? The git repo (https://github.com/cdnjs/cdnjs/tree/master/ajax/libs/moment-timezone/0.5.34) would indicate this file has never actually existed?

Hey Matt - thanks for sorting this. We raised an issue with the folks at TTNmapper-website <https://github.com/ttnmapper/ttnmapper-website/issues> who could answer your question re file never existing (ie change at the mapper end) - yet to get a reply. We noticed the change in behaviour of the ttnmapper code maybe a week ago. It sas working reliably, then a week ago - it started not painting map tracks - which we traced to this dependency Thanks Paul.

Still unable to review the trails and testing from individual ttnmappers - due to this issue.
I note the overall heatmap is working - just device specific tests.

I've escalated this before, but I'll poke some folks again.

Interestingly, it looks like this file still exists in the cache partially, which confirms this file did exist and has disappeared:

cc @xtuc looks like some files have disappeared which seems quite major, I suspect this happened with the R2 migration?

[paularthur]

ttnmapper-website code has been updated to use a more recent library - so we're up and running.
I confirmed the 404 on the older library is still there - but its no longer a show stopper for us
Matt - Thanks for your help.

Just to circle back, I've further escalated this to try and get some eyes on this from the Cloudflare side, as files should never, ever disappear from the CDN.

[MattIPv4]

This is now being tracked in ticket #2920331 with Cloudflare (marked as high priority). It has been acknowledged that they are investigating it, but they cannot share details with me...

[MattIPv4]

👋 Synced up with folks at Cloudflare over the last few days, and this is now getting significant attention internally (both to rectify this issue, but also generally around maintaining cdnjs and comms). Apologies for the delay on this.

Good news for this issue, cdnjs has been switched back to the KV data source, rather than the R2 bucket that it recently migrated to. This file (and others there were missing from the R2 bucket) should now be back and avaialble for use on sites!

The team are still investigating why exactly these files are only present in KV, and not in the R2 bucket and git. I'll share more updates here once I know more from them, including what the plan is to fix the R2 bucket and switch to it again at some point.
