On Monday, I did the jump puzzle and was unable to open the vault. I have since tried each day this week, and it will not respond. I have also stood by the door with others who could not open it.
I was just waiting for a server reset to fix it, but after going in this morning, it is still bugged. At first I thought that maybe it was because I had “old” key halves, but as I was contemplating chucking the key halves and re-doing the jumping puzzle, another person ran up who had just gotten them and it wound’t open for them either.
I am on Henge of Denravi server, but I saw a few posts in the WvW sub-forum stating that some other servers were having the same problem…It seems like more of a “bug” issue than a WvW one, so I put it here. Anyone else confirm here that it is or is not working for them?

Keep an eye on that one and rest assured that the team is working on this.
