  • Problem:

Many subnets belonging to colo/hosting service are globally blocked in order to stop spam or per NOP. Several legit users/organisation may be affected if they use private VPN, private proxies which are caught by these blocks. Currently the only way to unblock a single IP is chunking the relevant rangeblock in 32-blocked prefix lenght blocks (for IPv4).

  • Who would benefit:

Legit users caught by proxyblock, stewards saving complains to give answers and administrative overhead in managing the block of many smaller subnets.

  • Proposed solution:

Allow a global whitelisting of IPs (or even ranges) included in a globally blocked subnet.

Discussion[edit]

Is Global IP block exemptions insufficient? Anomie (talk) 14:58, 9 November 2017 (UTC)

Nope, GIPBE is a big deal since it allows an user to edit from *any* blocked connection, also it obviously only works for registered users. --Vituzzu (talk) 10:49, 14 November 2017 (UTC)
Not at all, there are 900 wikis where it would be potentially needed. An example, I just got an email from a local US government which offers a free wifi service. The service uses a captive portal hosted in a colocation facility. Colocation subnet is blocked because it also hosts several open proxies. How would you solve this? --Vituzzu (talk) 10:49, 14 November 2017 (UTC)
By not blocking entire subnets because they include "several open proxies"? --Tgr (WMF) (talk) 00:55, 17 November 2017 (UTC)
Did you ever dealt with spambots floods or our loyal LTAs? --Vituzzu (talk) 10:07, 17 November 2017 (UTC)
Yes, although no doubt on a smaller scale than large wiki / crosswiki antiabuse people. My point (made in a flippant tone that was uncalled for; sorry about that) was that if a block is sweeping enough to include important institutions that we notice we don't want to block, then it's probably also going to include lots of "unimportant" well-intentioned users whom we won't notice. It would be better to think about improving block targeting instead of issuing wide blocks and whitelisting a lucky few. --Tgr (WMF) (talk) 06:34, 19 November 2017 (UTC)
Well, I made just an example, but most of complains are from single users, usually those using their own VPNs. Rangeblocks are not indiscriminate, I usually don't block transit while I usually block webhosting. Also, a significant percentage of users caught are actually affected by some fancy malware.
What I am proposing here is not meant to be a general purpose solution, but another tool to ease the handling of the big burden of crosswiki issues. A tool which would be, in my experience, the "cheapest" way to solve a variety of problems. --Vituzzu (talk) 20:51, 19 November 2017 (UTC)
