I confirm as steward that I couldn't remove either the global block on itwiki;
but I could at testwiki
https://secure.wikimedia.org/wikipedia/test/w/index.php?title=Special%3ALog&type=gblblock&user=Dferg&page=&year=&month=-1&tagfilter=.
Stewards have the ability to remove global blocks locally via the global
'steward' group; something wrong happens here.

Forgot to say that it is still http://it.wikipedia.org/w/index.php?title=Speciale%3AElencoBlocchiGlobali&ip=151.49.0.0%2F18 locally active. When you whitelist it locally the message above contains "locally dissabled" or similar.

I don't understand the problem. The screenshot says that the block is already locally disabled, doesn't it?

According to the database, it is indeed already disabled on itwiki

mysql> select * from global_block_whitelist where gbw_address='151.49.0.0/18';

Are users still being blocked from that range?

No response to Andrew's query, so I'm assuming this can be closed.
