\section{Sharktech}
Sharktech is a provider that focuses on DDoS prevention, such
as for gaming servers. Has a data center in Denver.
Looks good. Manually provisions servers over a few days.
Good local speed and latency.

First login, kernel is:
\texttt{Linux debian 3.16.0-4-amd64 \#1 SMP Debian 3.16.36-1+deb8u1 (2016-09-03) x86\_64 GNU/Linux}
It isn't up-to-date. Running Debian 8.6. The \texttt{dmesg} showed the kernel had already
barfed a couple times (USB time outs and more).

IPMI http connection is in cleartext!!! Doesn't redirect to https. https has failed SSL
certificate (like every other Supermicro on the planet). IPMI requires Java junk.
Server was running for a few days before I could update it.

\begin{itemize}
 \item Default IPMI connection is in cleartext http.
 \item SSL certificate for Supermicro IPMI is bad (like all of them).
 \item Can't change password on IPMI.
 \item Root password for server and IPMI is sent via email.
 \item There is an attack window between their machine imaging and first login.
 \item Customer should control timing of first power on.
 \item System is also possibly vuln during the ISP's initial power up and commissioning period.
 \item First reboot, the system hung (.png XXX).
 \item Hard reset, lots of DHCP queries at boot.
 \item A \texttt{debian} user was on the system, password unknown. Check \texttt{/home}!
 \item They block NTP to prevent DDoS, so you have to use their time server
  \texttt{time.sharktech.net}
\end{itemize}

\begin{itemize}
 \item Credit Card.
 \item PayPal.
