After rankings a LOT of websites high on the first page, for medium to high volume keywords, I have noticed a big trend. They always seem to rank very high on the first page, but only on certain data centers. They stay on page 2 on most of the other data centers (IE: if I check the ranking on my VPS, etc. etc.) Anyone else notice this? Its like clock work. How long does it usually take for it to rank the same on the other data centers? Assuming that you don't bounce back or get sandboxed. Also, many times it seems the site is sandboxed on most of the data centers, but ranking awesome on some data centers... drives me nuts.
