This may be a tad low budget - but - assuming you can even get a steady reliable signal at your Data Center, you can try Franklin T9/T10/R910 hotspot device which runs off USB with battery removed 24x7. Will use a 4G connection and static IP through T-mobile. You can connect a UMPC or old Dell laptop with RS-232 serial or USB console cable to your KVM device. We use this at some remote colocation client sites and it has worked perfectly for over a decade. In the colocation space you can also try a cross connect to another AS, some are willing to barter a simply 10-100M connection to one another over copper in the colo space, so both parties can gain access to out of band. However this could get pricey with sites that charge $375 like Equinix.
