Rate limit hit of check.tpo on 'new identity' in Tor Browser
Remove hit of check.tpo on 'new identity' in Tor Browser. Since this new feature went live a few weeks ago, the requests per second on check.tpo has doubled and shows no signs of abating. The server is increasingly busy. See https://munin.torproject.org/torproject.org/sergii.torproject.org/apache_accesses.html (use tor-guest username and anything for the password). The next time the server crashes, everyone will be sad, even more so than before.
Option two is to remove check.tpo completely and have it done via the browser.
