At the end of last year we switched off cloudflare CDN and implemented our own caching servers. At that time we were doing around 130TB of throughput (including what was being soaked up by Cloudflare). As of last month we did 430TB of throughput without the help of Cloudflare. </div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large"><br></div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large">We are trying to optimise costs - that bandwidth alone cost us in the neighbourhood of 500€ per month. To reduce costs we can approach the problem in two way:</div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large"><br></div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large">1. optimise the infrastructure - we (QGIS Devops team) are busy looking into ways to do that...</div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large">2. reduce the download size...</div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large"><br></div><div class="gmail_default" style="font-family:arial,sans-serif;font-size:large">We are wondering if the datum shift files could be split out from the main installer and fetched as an optional extra? Or maybe on demand as you need them? We could set up some infrastructure for hosting them, but we would need some help on the application side to implement logic to go and grab shift files that are not locally cached.
