Does OSM have SLA? > No, we're doing the best we can. The point is when you distribute your storage to people at home we will have at most 10% of images online all the time. So the user experience clicking on images will be awful so nobody will use it. Disregarding the case that upstream bandwidth internationally is pretty bad so you tend to have access times for images of about 4-5 seconds at best. (3MByte image at a typical ADSL upstream with 1.5MBit/s and international latencys) Flo -- Florian Lohoff f...@zz.de UTF-8 Test: The 🐈 ran after a 🐁, but the 🐁 ran away signature.asc Description: PGP signature ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Hello, Le 26.06.20 à 12:42, Florian Lohoff a écrit : > this is NOT a trivial no one said it is trivial, or it would be over by now. but some of us try more positive alternatives than "sitting down and doing nothing because it's impossible". maybe it will succeed, maybe it will only be 1/10th of what is hoped for, maybe it will not succeed. with this in mind 20k€/year for storage is one to explore. distributed storage, too. I don't care about SLA. Does OSM have SLA? No, we're doing the best we can. today, it is easy to make a map for your own photo storage. it's also possible to make a thematic instance for a local community. it's possible and easy to feed it from your mapillary account. it's already not so bad! i don't remember osm starting with a 100k£ call before the first test. thanks to the precursors for not being aware that it's not a hobby pet project someone is running from his/her basement.

And you honestly suggest a distributed system? What is the availability for the images - Did you say SLA? I am doing IT Infrastructure for 25 years now and this is NOT a trivial task and it is definitly not a hobby pet project someone is running from his/her basement.
