All public proxy's are currently flushing actively (direct) or on a weekly interval. The flushes we have seen today are the result of an internal race: which subteam is the first to flush a million blocks on a day. Although the subteam Graasland announced their flush, an other subteam or individual also flushed his proxy, resulting in two members with a daily total of over one million each Since there were a lot of subteams racing for the million, it is likely that we will see 1.5 or 2 million flushes before the end of the year (they have to flush within 90 days, give or take a few, to keep their blocks valid)
