The 2 places I know of that give an indication of what the "mempool min fee" likely to being currently used by default nodes
You can also see this on Jochen's site by using the "BTC (default mempool)" option at the top, rather than the "BTC" option. Itnis quite nice to be able to compare the two and see just how much is being purged from default nodes. At the moment it is about 125 vMB of transactions.
