Yes, We Are Still Open

We’ve heard a rumor that Roller Network was closed for business, however, that’s not true. Since we own and operate our own infrastructure (we don’t outsource anything), if you’re reading this then we’re here and we’re online. Or you can call our office at 775-284-0383.

Roller Network is a locally owned and operated company in Reno, Nevada offering a line of technically-oriented Mail/DNS services since 2004. In November of 2009 we were pleased to open our facility to the public for colocation services in a market that has traditionally lacked professional, carrier-style services.

Q&A: “Do your walls extend past the ceiling?”

One question we’re frequently asked on tours is if our walls extend (or “cut”) past the false ceiling. The answer is yes; all of our walls extend the full height up to the floor of our mezzanine level, and the remaining overhead spaces are too narrow for someone bypass doors by going through the ceiling. At the same time, we do not permit unescorted site access.

Full walls cutting the false ceiling.

Many times businesses will save money on construction costs by only building up to the bottom of a false ceiling, but since our facility is an integral part of our services we always opt to cut the ceiling. We also dress overhead wiring with d-rings even though it’s hidden.

File Into Folders with Hosted Mail Extensions

A question came across the forums last week about address extensions (user+ext@example.com) not working because it wasn’t filing into folders automatically based on the extension part. They do work, but that anticipated behavior is actually a modified one rather than standard, but such a thing can be accomplished with Roller Network hosted mail boxes and a quick Sieve script:

require ["fileinto", "variables"];

if header :matches "Delivered-To" "user+*@example.com" {
  fileinto "${1}";
else {

Add this using the managesieve online interface (or managesieve plugin that allows direct entry), replacing “user” and “example.com” with entries appropriate to your hosted mail box. This script will automatically file anything with an extension into a folder of the same name or default to INBOX if there wasn’t an extension.

We have been considering adding this functionality as a per-mailbox account control center option, but a Sieve script will quickly do the job just the same without having to wait for us.

Yes, We Have a Whole Facility UPS

We’ve given a surprising number of tours lately for colocation where one of the questions brought up was whether or not we provide UPS power to the racks. The simple answer is yes: Roller Network maintains and provides facility-wide UPS power. There is no requirement for a colocaiton customer to provide their own UPS. It’s actually our site policy that all switchgear, batteries, and UPS systems must be isolated in the electrical room separate from other equipment.

Apparently the motivation behind this question is that many of our local competitors do not provide UPS power for colocation. Well, we do, and we see it as part of our job in providing colocation services. If you have to maintain your own UPS and batteries, why colocate in the first place?

Primary DNS and Zone Transfers

We’ve received a couple questions about zone transfer (AXFR) support for our Primary DNS service. Currently we do not have AXFR enabled on the DNS servers that answer requests for Primary DNS zones.

The AXFR limitation is not intentional; unfortunately it’s supported by the DNS server. Primary DNS is served using PowerDNS authoritative server version 2.9.22. It does not support per-zone AXFR ACLs like BIND9 does.

The only option we have would be to allow AXFR to anyone, but for security reasons we don’t want to do that. We can’t globally allow our Secondary DNS to AXFR because that creates a backdoor where anyone with an account could use it as an intermediate AXFR host. (Security aside, most of our customers don’t want AXFR open to the world or IP addresses they don’t control.)

PowerDNS authoritative 3.0 is currently in RC2 stage. This version does have per-zone AXFR capability and we will support it in the control center as soon as possible. It also has other features we’d like to add like DNSSEC and long TXT records.

We’re working on changes to the control center required to support these features but ultimately it requires the servers themselves to be upgraded to either the release candidate or the 3.0 release to support them.
