Hello everyone: * DNS does not have a "refresh rate". In DNS, the person running the domain determines what the "refresh rate" (it's called TTL in DNS) for their records is; for example, Google has a TTL of "once per hour" and my domains (maradns.org, etc.) have a TTL of one day. * As mentioned before, Scientific Linux 6.0 is out. What hasn't been mentioned here is that while SL 5.6 hasn't come out, 5.6 security updates are being backported to SL 5.5. Ditto with SL 4 (no 4.9 but security patches look current) Take care everyone, - Sam
