Use this file to get the CRS definitions you need in southern Africa, particularly South Africa, Lesotho, Swaziland and Zimbabwe.

Most GIS software now implements the South African CRS (SACRS; incorrectly but popularly known as the "LO" system) which is based on south-oriented (or south-facing) transverse mercator (TMSO). The EPSG codes for these are:

• odd numbers from 22275 to 22293 for the Cape datum
• all numbers from 2046 to 2055 for the Hartebeesthoek94 or WGS84 datum.

If you have data in one of these south-oriented CRSs it will draw upside down and back to front in its native CRS but if you have on-the-fly transformation enabled, your layers will overlay your other data perfectly in whatever project CRS you choose. This feature request will result south-oriented coordinates and visualisation being more intutitive to GIS users.

Note on datums: Although there are a few metres difference between the WGS84 and Hartebeethoek94 datums, for all intents and purpos

Non-technical route

1. Check FIRST if your domain is on the 3rd party suspended list: http://firefishy.com/orgza-domains-suspended-05092016s.txt if not then this guide is not for you.
2. Ask the company who registered your domain to sort it out. They will likely charge R100, if wildly more they are ripping you off.
3. Once they have started the transfer process check https://www.registry.net.za/whois/ to see if your domain has "Domain Status: pendingTransfer", if not return to step 2.
4. Once in "Domain Status: pendingTransfer" transfer process takes 24 hours + 8 hours for new records to become valid.

Subject: Disruption of OpenStreetMap Access

Hi All,

OpenStreetMap.org is currently suffering from a partial outage due to a major denial of service attack against the UK Academic Network.

The outage mostly affects those outside of the UK. An outage like this is extremely rare.

The operation team will implement a workaround if the problems persist.
