mrkgnao: More or less, everything. I don't think there's a single GOG feature that MaGog looks at that hasn't intermittently but catastrophically failed in the past 24 hours. This is a new level of bad, even for a big GOG sale.
A pity, because in the past couple of months I got the impression that things were getting better and faster, structurally speaking, perhaps as a result of GOG investing in infrastructure. Not enough, I guess.
Sure didn't seem better and faster to me for weeks now, if not months. There seem to be periods, especially at night my (and their) time, when the site is awfully sluggish, to the point of a forum thread taking minutes to load. And today I guess it was the giveaway, times when it didn't work at all and didn't even turn up a GOGbear, but a plain 503, so obvious overload, when loading full pages, or nothing whatsoever on content supposed to load dynamically.
