On Wednesday July 1, 2009, at 1:00PM, teleporter.cc.gatech.edu and timewand.cc.gatech.edu, the College's secondary DNS servers were unable to resolve the .gov top level domain. This would have affected any CoC faculty, staff, or student system configured with teleporter or timewand as a DNS server, trying to access the .gov top level domain. On July 6, at 9:15AM, the issue was resolved.

Update: After further investigation, TSO has concluded that the following domains were affected during this outage:

.gov
.museum
.pr
.br
.bg
.se
.cz

Email sent to or received from any of these domains was rejected during the outage from Wednesday, July 1, 2009 at 1:00 PM through Monday, July 6, 2009 at 9:15 AM, with a rejection notice being returned to the sender. Any attempts to reach any of these domains would have been unsuccessful, as well. .org was also affected but for a shorter period of time (see http://support.cc.gatech.edu/utilities/alerts/partial-dns-outage for details).

If you suspect that you should have received email from a user of any of these domains during the outage, please inform the sender to resend their email. You may also wish to resend any email intended for these domain addresses.

On Tuesday, July 14, we will be applying a patch to prevent such outages in the future. Details on the system notice can be found at http://support.cc.gatech.edu/utilities/alerts/dns-server-maintenance.
