The answer is a bit complicated, as there are a lot of factors involved. To some extent your experience may be in part to the server you spend most of your time on, some servers are more stable than others. Generally paid DLC maps (Scorched Earth, Aberration, Extinction, Genesis) tend to be a bit more stable but, again a certain server could just be in bad shape regardless of the map. Keep in mind that at each server save, which happens about every 15 minutes (this is the same as the timer on transferring or uploading), there will be lag spikes which will can be much longer if there's a lot built up on the server.
There is also the winter event going on, and any event will usually take a toll on official servers. Between more people active and especially if there's a lot of breeding/raising going on.
The disconnects do happen occasionally, but since the mega boosted rates for the charity event and TLC patch they seem to be much more frequent on pretty much all official servers. There could be a bug causing it, but honestly no players would really know whats going on with it.
Finally as you're on pvp, it's worth noting that there are... reasons... why some players or tribes may want to purposely induce lag/crashes. I'll leave it at that
