At my workplace: Jira is all over, sometimes customized and tweaked, but we could be convinced to switch. Jira licensing has become a big problem. For security reasons, we have dozens of little disconnected networks. Each one needs a separate server with a separate license, purchased separately. All software updates have to come via physical media, typically a DVD-R. That's way too many enterprise licenses to purchase. It's like that with all types of software. If we want Ubuntu updates, we mirror the entire Ubuntu repository onto physical media and then carry that into the room. The physical media is then destroyed, even if it is a hard drive. You're not getting info out of that room. Usually we want to deploy on a plain Ubuntu box. Sometimes we might use VMWare. Network speeds are normally fast, but sometimes a whole-network VPN (not browser based, not on a workstation) connects sites that are 1000 miles apart. Be sure to always test your software with high network latency.
