Hi OSM, The OSM tile server has been upgraded over the last few days. Changes should now appear much quicker on the map.
Many thanks to Jon Burgess, the Mapnik.org guys and the others for making this happen. Technical: The rendering database was switched to an Intel 320 Series 600GB SSD disk, from 4x 300GB 10K rpm in RAID10. PG8.3 -> PostgreSQL 9 with GIN Index FASTUPDATE disabled. Rendering has also switched to Mapnik2 svn r2875. The full DB reload into PG9 used approximately 1TB of the SSD write capacity of a rating of 60TB. Now that only diffs are being applied the write usage has dropped drastically. We'll watch the write usage. Some metatiles are being moved across to the 'old' RAID10 array to improve overall tile IOPs.
