My friend was having very bad connection issues on and off all night last night (Sat). It was pretty late too so there were only ~500 people on shadowdale. Also, it wasn't his internet since his discord and other stuff was fine, it was just DDO.
My friend and I were fine for most of the night, but then the 2 of us (roommates) got the same yellow connection, with a ping of 1000+ instead of our normal ~10, for 5-10 sec like the other guy was getting. Think it only happened once to us in the ~4 hours we played. And to my friend maybe 10x
