Hey Little_Quill, thanks for reaching out and I am sorry to see what happened there in the match which you've provided a clip for.
So that we could get a better idea about this, can I ask you to clarify the following:
1. Is that first instance this happened or did it happen before too?
2. Are you aware if there are any particular steps to follow that may cause this to occur? Only reason I'm asking is because I can hear people saying that they enemy team "glitched it".
3. What time did this match take place?
After having a closer look at our server status, I can see that we've had a temporary degradation that has been affecting multiple platforms and games, including Rainbow 6 Siege, however this has been resolved since and servers are working as intended, therefore can I check if you were all able to connect to a match after the disconnection occurred?
Let us know and we will take it from there!
