DNS failing for VPS40

[infantex]

Hello.

I've been receiving e-mails since yesterday with the following message.

sudo: unable to resolve host vps40.heliohost.us: Temporary failure in name resolution

What should I do to remedy this?

Regards,

The DNS records are set correctly

root@tommy2 [/home/krydos]# dig +short A @ns1.heliohost.org vps40.heliohost.us
65.19.141.197
root@tommy2 [/home/krydos]# dig +short A @ns2.heliohost.org vps40.heliohost.us
65.19.141.197

Is the issue still happening or was it just for a few minutes? There have been three 160 Gbps DDoS targeted at Tommy2, our main website, and forum over the past 24 hours so that may have caused short disruptions in your DNS, but they each lasted only 10 minutes or so.

The issue keeps happening every two days or so.

For example, I just received 30 of those e-mails in the lapse of three minutes.

There is another DDoS happening right now so that would explain the emails.
