Answer 1

So like most things in life, this was my fault. Historically we had 2 systems for getting data and never really finished moving to the latter. One of those artifacts came up with some Developer Timeline work that showed us doing an unnecessary HTTP request to the 2.0 API to get your user list for the Communities section of the profile. There's no need for that overhead, we've got database access.

We also didn't need to cache the number of strings returned with a !8.(3p54UxIbJyv5MuonC6aUPxvldcj7CbjQXT8 filter, since we have the sites readily available in local cache all we needed was an integer. So we could save time, an HTTP request, deserialization time, allocations, redis wire time, and memory all by switching over to a faster database query.

Paired with this was code cleanup: moving these methods from User since "getting other network users" didn't really belong there, to Account. That's where this line of code didn't get changed:

Hooks.UserReputationChanged(Id, user.Reputation, Current.Site.Id);

It should have been:

Hooks.UserReputationChanged(user.Id, user.Reputation, Current.Site.Id);

So...my bad. It should be fixed as cache expires since the place this happens is in the correction logic. This section of code was written to sync up what you see with what is returned. Since the network-wide aggregation can lag up to a second we need to replace the current-site data in the return set to match your top bar so it appears in sync. If a difference is detected, we also issue an aggregator request to fix it...just in case. That's the code that was getting hit here.

If anyone has more questions I can clarify a bit, I just thought some background on how this works may be helpful.

Answer 2

I found a pretty strange coincidence, after having seen @Sha's comment. The network-wide profile of ewwhite has this link:

http://stackexchange.com/users/270504/ewwhite

And yours Server Fault profile has the same id:

http://serverfault.com/users/270504/beatcracker

This is weird, but could be the reason (and probably someone's else has been also affected).
