If this is only Windows XP in SauceLabs then it's low priority (WMF does not run any browser tests at SauceLabs on Windows XP). I would appreciate it if someone could try IE7 or IE8 on Windows XP outside SauceLabs.

@BBlack, is T147199: Removing support for DES-CBC3-SHA TLS cipher (drops IE8-on-XP support) going to make this impossible now anyway?

@Whatamidoing-WMF - Kinda? See also the explanation here: T25932#3614933 . TL;DR is that just because we removed the cipher that IE8/XP should use, that doesn't necessarily mean that no IE8/XP clients will ever connect to us.

Going by https://www.mediawiki.org/wiki/Compatibility/Software_for_using_MediaWiki#Grade_B , currently IE6-8 seem to all fall into the Grade B category of support. But I think once this 3DES deprecation is done, chances are good that at least the WinXP versions of those will be <0.1% and should be removed from Grade B. However, https://stats.wikimedia.org/wikimedia/squids/SquidReportClients.htm doesn't break down by underlying OS version, which is why IE8 is higher there (it's including e.g. IE8-on-Vista and others).

FWIW, that's deprecated, https://analytics.wikimedia.org/dashboards/browsers is the (much fancier) replacement that can also provide OS/browser combination statistics.
