They used to have transfer based pricing but then moved to bandwidth based, reps said to simplify billing. Their new KVM service gives you 1g burst and 100mbps average by default. https://glesys.com/vps/pricing is very straightforward.

At my previous employer we migrated to them and were very happy with the VMware infra they provided.

Since It's a Swedish company one can look into their economy to see that they're not going anywhere. https://www.allabolag.se/5566479241/glesys-ab

I don't recommend them. We used to host an online text game there (MUD) and when one of the players decided to DDOS it, Hetzner just pulled the plug. I moved to soyoustart.com (it's OVH brand) - in following month they sent a couple emails about the server being attacked and that they're trying to mitigate the attack, but game kept working.
