Do you have ad blocker or script blocker plugins running in your browser?
I'm not the person you're replying to, but I visited the site ealier from my laptop and I was just getting an error accessing the shop page. I get the same now on my desktop.

Using Chome instead of Firefox worked. I do run a script blocking add-on in Firefox, but it wasn't signalling anything was being blocked.
Very tempted to get this new model, but I don't have the budget for one right now. I have one I bought from Doug in 2012, which is reading 240uV high (well within the 5V +/-0.01% spec), and within 100uV of my notes from 3 years ago when I bought my 34465A (which may have also drifted). I also have a 3V reference from Doug also from 2012, which reads 280uV high, just inside the 0.01% spec.
Edit: I wouldn't be surprised if they're both pretty close to original spec, and the offset is in the 34465A considering its one year spec is 0.0034%. Good enough for my purposes, but I should get my 34465A cal'd at some point.
Edit 2: Actually, just compared the 34465A and my 34401A, and they agree to 1 LSD (34401A reads 10uV higher) - and I think the meters are probably more accurate long term so I'll believe them. All my other meters are 5.5 digit or less, and the two quite new R&S HMC8012 meters also agree. 121GW & BM869S both read high, but still damn close. I'll check my three old 3478A's later, but I know one has drifted compared to the others.
