I just spent a good while attempting to do the arms dealer strike for the Leviathan's Breath quest step and after finally getting to the boss and having him half health the servers go down. I'm fuming right now, I've just recently got back to playing Destiny 2 after 2 years away and spent money buying expansions, the least I expect is stable servers, I've now just wasted time out of my life doing an already stressful quest step just to lose my progress because Bungie can't keep their servers up, it's ridiculous.
