VeriSign was directed by ICANN to suspend the Site Finder service by 0100 UTC on Sunday, October 5. We requested an extension from ICANN to give more notice to the community but were denied. We will be removing the wildcard A records from the
.com and .net zones beginning at 2300 UTC on Saturday, October 4. The former behavior for these zones (returning Name Error/RCODE=3 in response to queries for nonexistent domain names) will be in place by 0100 UTC on Sunday, October.
