Search Again: Load Balancing question From: Suzanne Swift Date: Wednesday, July 3, 2002 Time: 6:19:56 am I have two Web servers A and B. Quick DNS is set up to load balance so that 99% of the load goes to A and 1 % to B. I ran a DNS system test and took my primary DNS server off-line. Both Web server A & B were still on-line. When I did a DNS look-up for four of my host names - all were being pointed at server B (the 1% server). I then turned the primary DNS server back on and checked 7 hosts. 5 were now pointing at server B and two at server A. I checked again the next morning and six domains were pointing at server B and only one at server A. Finally, approximately 24 hours or so after turning the primary load server on and off, I checked the seven host names again: all seven were now pointing at server A. My primary host name settings (I run virtual hosting) are: Refresh: 28800 Retry: 7200 Expire: 604800 Minimum: 86400 Time-to-live: 86400 The Load balance record settings are: Interval: 30 Hostlife: 60 My question is: Why does the DNS shift the load to Server B when the Primary DNS machine goes down? Is there any way to prevent this from happening? -- Thanks, Suzanne
