I fully agree with Rob. Another possibility: make it configurable at what time of day my server is in the pool (or "more/less likely" instead of "on/off"). Companies donating servers use their bandwidth during working days, but are available in the evening, at night and in the weekends. Home systems, like mine, should be responsive during the evening and weekend, but I don't care about a heavy load at night or during the day. > Of course, the shorter the TTL the higher the load on the DNS servers > from these folks. If a server is only once in a response, then you are in the cache of one ISP's DNS. Even if the TTL is the same, I guess, it would result in far smaller peaks than when you end up in the cache of many ISP's at the same time.
