We need more information to investigate this issue.

If this happens again: please check if turning off/on wifi resolves the issue? 

Another thing that can be done is getting mDNSResponder logs:
1. Turn on verbose logging with 
a) sudo syslog -c mDNSResponder -i
b) sudo killall -USR1 mDNSResponder
c) sudo killall -USR2 mDNSResponder
d) syslog -w > ~/Desktop/mDNS.log
2. Let the following `tcpdump` command run in a terminal window to collect a packet capture:
          sudo tcpdump -w ~/Desktop/dns.pcap 
3. Reproduce the problem and take note of the time problem reproduced
4. Stop tcpdump with Ctrl+C
5. From Terminal, execute  '/System/Library/Frameworks/SystemConfiguration.framework/Resources/get-mobility-info'
6. From Terminal, execute '/usr/bin/sysdiagnose’
7. When you’re done, turn off verbose logging by rebooting OR 
sudo killall -TSTP mDNSResponder 
8. Files to collect:
~/Desktop/mobility-info*.tar.gz
 /var/tmp/sysdiagnose*.tar.gz
~/Desktop/dns.pcap
~/Desktop/mDNS.log
