- chrisstanchak 7y agoCDN costs must be negligible compared to the cost of managing that.
- jasoncartwright 7y agoPotentially the expensive cost they would mitigate is the mobile data
- gleenn 7y agoI think it only upgrades over WiFi? I remember someone complaining that it was difficult to upgrade because of network issues.
- jasoncartwright 7y agoThey prioritise upgrade downloads over wifi, even faster over service centre wifi (from my experience)
- lazyjones 7y agoYep, I hide my 2nd phone with a power bank in the car sometimes just to provide an AP for the car to initiate a download (it's in a public garage with no public WiFi nearby).
- readams 7y agoI think they stopped doing the service center wifi thing. It used to be if you just parked in front of the service centers you'd get the update right away, so of course too many people were doing that. Now you can just select the option to get the software update right away though.
- andrewstuart2 7y agoPretty sure the infrastructure for what they already have would dwarf the costs of adding WAPs and adding some caching software to whatever computers they're almost certainly already managing at the superchargers.
- londons_explore 7y agoCloudflare is 100% free for this kind of thing. No need for a company to ever consider distribution costs again.
- FireBeyond 7y agoCloudflare is certainly not free for distributing multi-gigabyte binary blobs. Their free bailiwick is "website content". You might fly under the radar at small scale, but any corporation is not going to get to use CF for free to handle that kind of distribution.
- londons_explore 7y ago> Cloudflare is certainly not free for distributing multi-gigabyte binary blobs. Citation needed. I've been using it for distributing all kinds of things like that and never paid them a penny... Just make sure you split it to 512MB chunks, which isn't hard for a software updater.
- aledalgrande 7y agoYes, I imagine many security problems with local deployments.
- somebodythere 7y agoThe code should be signed anyway.
- ofcrpls 7y agoSome telematics firmware downloads already use this https://en.wikipedia.org/wiki/Multimedia_Broadcast_Multicast_Service https://en.wikipedia.org/wiki/Multimedia_Broadcast_Multicast...
- _underfl0w_ 7y agoImagine how easily one could spread a fun new kind of worm by compromising an unattended firmware download mechanism if one were so inclined. Food for thought.
