Content Scanning for Forwarding

Effective immediately, content scanning will no longer be optional if the “Mail Forwarding” option is enabled for a domain. If forwarding is enabled, SpamAssassin and anti-virus will automatically be enabled as well. A future update to the ACC will indicate this override on the SpamAssassin and anti-virus configuration pages.

This change is being made in an effort to reduce the amount of potentially undesirable email that is being forwarded to external sources through our services. It is not acceptable to forward mail unfiltered and expect the forwarding destination to do the filtering since we are being marked as the source.

Partial outage on “mail.rollernet.us”

For reasons unknown at this time, it appears that MX mail.rollernet.us was refusing connections on port 25. We have since corrected the problem by restarting all potentially affected Postfix instances.

Because to this, we received several reports from customers who only had a single MX record configured. This is not a supported configuration. By using both MX records, they are designed to compliment each other in the event a fault in one prevents it from processing incoming mail. The two pools are unique, making it highly unlikely that a fault in one will affect the other. This is not a strict requirement in that we’ll refuse to help, but it is to your benefit to configure both. (We will refuse requests for outage credits, however, because it is in the help docs to use both.)

In order to maintain the highest level of service possible, please ensure that you are using both MX “mail” and “mail2” MX records. Customers that have both did not experience any interruptions.

[UPDATE] The cause is believed to be memory exhaustion caused by a debugging statement that was accidentally left in. This was a procedural error on our part as the debug should have been removed when the trouble ticket it was associated with closed.

Colocation Services Pricing

We finally have a page up on the main website for colocation pricing:

http://www.rollernet.us/services/colo.php

Following in the footsteps of doing something unique to stand out from the pack, rack space is free and we only charge for bandwidth and power. If you have an 80PLUS certified power supply in the server you want to colocate, there is a discounted rate for being energy efficient.

If you’re looking towards the future of internet access, our colocation services have been dual-stack IPv6 enabled since 2005. We also use 208V circuits standard – including three phase – enough power to load a full rack. For our international audience this isn’t much of a surprise, but here in the USA a 120V single phase outlet is the status quo. A typical 20A 120V from other providers only gives you 1920VA. At 208V, we give you 3328VA to use, and that’s just the minimum.

We’re proud of our services and we apply the same standards to colocation that we have with our email services. If you have any questions or would like more details, contact us.

IPv6 Changes

We have begin the process of migrating our legacy IPv6 network into our /32 allocation, 2607:fe70::/32. Once this is complete, we will further enable other services with IPv6, such as incoming mail.

If you’d like to test it, you can use 2607:fe70::1 as a ping or traceroute destination.

New Circuit from Global Crossing

We have no idea why there is such a lack of progress with Verizon, so we ordered a short term 6M multilink T1 circuit with Global Crossing as a band-aid. While we are keenly aware that it has no hope of fully taking over from a complete failure of our high capacity circuits, the idea is at least we won’t be completely off the air. It also brings something important to the table on its own: native IPv6. Global Crossing, while one of the more expensive providers, is well known for IPv6 support.

Over time, we will most likely replace it with one of their Ethernet offerings (if available) or at least another DS3. The multiple DS1 circuits simply have the shortest install time frame to our mux. If the Verizon circuit ever does get installed, we’ll probably never dare to make a change lest we wait a year for it to happen.
