It's Always DNS
Samuel Heinrich
TextLyrics
Verse
They call me up, the network is down,
everybody staring at the blinking crown.
Ping is clean and the routes are fine,
but the hostname vanished from the line.
Pre-Chorus
Check the cable, check the port,
check the firewall report.
Trace complete, no mystery,
then I ask: what about DNS?
Hook
Dig it up.
TTL.
NXDOMAIN.
Who can tell?
Resolver says no,
cache says yes,
welcome back
to the DNS mess.
Chorus
It's always DNS,
not the switch, not the mess.
It's always DNS,
why do we always guess?
Verse 2
Cache is old, TTL too high,
split brain zones make admins cry.
Forward lookup, reverse pain,
CNAME dancing in the rain.
Bridge
Flush it.
Query it.
Dig it.
Fix it.
Not the network.
It's DNS.
Final Hook
Dig it up.
TTL.
NXDOMAIN.
Who can tell?
Resolver says no,
cache says yes,
welcome back
to the DNS mess.
Final Chorus
It's always DNS,
from the helpdesk to the stress.
It's always DNS,
close the case, confess.
