Some users return 404 page on their reports

[russellbanks]

Bug Description

Some users return 404 when creating a report or just load indefinitely when calculating normally. I think this could be down to the users having a large history of activity on their account.

Reproducer

1. Input a user with a large activity history.
2. See 404.

Actual Result:

Returns 404.

Expected Result:

The result should be shown.

It seems this is caused by GitHub randomly returning 502 errors every now and then?

With some users sometimes it even works

RepoRank doesn't know how to handle this type of error so it just falls back to displaying 404, as for fixing in the short term, I'm not sure what to say, "Sorry GitHub is broke" doesn't seem right

As for the long term, I'll see what I can do to get around this error & report it

Because this happens with masses of activity I assume something doesn't work right with pulling all that data such as a timeout but this can't be the case as 408 isn't returned
