The following is a "last known" list of SAIX transparent proxies being used; these affect the great majority of internet users in South Africa (the proxies listed under "No contributions" are probably not part of the internet-facing side of the clusters):

Gauteng, New Doornfontein (ndf)
Gauteng, Randburg? (rba)
Western Cape, Bellville (ctb)
Western Cape, Cape Town, Barrack Street (cbs)
Unknown (ngy)

Whitelisting

edit

I've sent an email to Tim Starling (according to meta:XFF project), with the details of the proxies, and he replied that they have been whitelisted. So hopefully the problem is now solved. dewet| 08:23, 24 March 2006 (UTC)

Sent another email today to request addition of 198.54.202.5 (talk · contribs). dewet| 12:06, 5 May 2006 (UTC)
