Double compression?
« on: September 15, 2014, 06:01:00 AM »
Although Webmaster Tools isn't complaining about the sitemap, when I download my gzip'd sitemap and extract, the resulting sitemap.xml file is actually a compressed file again. If I rename it to .gz and extract again, the new result works correctly. Not experiencing the same issue with any other gz files I download. Same behaviour if grabbing the file with Chrome or Firefox.

possibly your server adds another compression "layer" on the fly. Please try to disable compression setting.

Turned out sitemap.xml.gz wasn't actually compressed at all, but an uncompressed XML file pointing to the sub-parts. Google is smart enough to process it correctly anyway but clearly my machine got confused.

Seems to me there is a logic error that happens when you have compression selected in config and the sitemap gets broken into more than one part.
