[Incident Report #033][DNS] Suspended lookups for ‘look.com’
What Happened?
NS2 has been seeing a low-volume, but constant stream of lookups for
‘look.com’ for the past few days. These lookups are for ANY and are spread
across a handful of IPv4 addresses. Seeing as most lookups only make a
handful of request before the requesting machine has the info it needs,
we are dropping these lookups for a little while because our NOC is treating
it as internet background radiation.
We were seeing the following issues:
- Steady, low rate, constant lookups for ANY against ‘look.com’
What did we do to fix this?
- Temporarily dropping lookup request for ‘look.com’

[Incident Report #032][DNS] SSL Expiry on NS1 and NS2
What Happened?
Our SSL certs for NS1 and NS2 expired earlier today. Currently our process
for handling the updating of SSL certs is not automated and requires our
team to manually install new certs and then reload the servers one after
the other. Usually this is on our internal calendar and is handled three to
four days before EOL. That didn’t happen this time.
We were seeing the following issues:
- Loss of DNS over HTTPS support
- Loss of DNS over TLS support
What did we do to fix this?
- We pulled new certs and updated the cert store
- We reloaded both name servers to restore service
Everything should be operational and peachy again!
