Q1-2016 Broadband Update: Bye Bye Global Capacity, Hello Tachus!

According to Bob Dylan, “The times they are a-changing.” I certainly hope so. I’ve made some changes to our broadband service hereabouts, and I’m hopeful about a new alternative. The details of these two things are worth sharing.

I’ve long held that someone in a technology business, who works from a home office full time, should have redundant forms of internet access. If you’re going to have redundant access they should use different modes of connection. That way a single errant truck or backhoe doesn’t take out both of your services.

This belief was strengthened by our own experience in events like Hurricane Ike in 2008. We lost Comcast service for several weeks, falling back to our stodgy old DSL circuit. The DSL meant that we had IP phones running the morning after the storm, when even cellular service was down, amazed and confounded our neighbors.

Our first broadband service to this location was a DSL circuit. The name on the bill changed numerous times. What started out as Sprint Ion devolved into Earthlink, then Covad, Megapath, and most recently Global Capacity. The data rate was slow, but reliability was high.

Bytes Must Flow – Backup Strategies for SOHO Internet Access

Late last evening there was a fire at Oxford & Barkley, or so we’re told, that took out Comcast service some neighborhoods in Houston, including where we live in The Woodland Heights. As such we are presently without cable TV or our primary internet access.

The loss of cable TV is potentially stressful for Estella, but she’s off to work for the day so it won’t be a problem until this evening. Given my home-office-based work-life the loss of internet access is potentially a show-stopper for me. It’s at times like this that I’m glad we have backup internet access.

Covad & AT&T: The Odd Couple Of DSL Make Good

DSL-ProvidersMy belief is that since your home office network is your network, and under your control, it should actually be more reliable than the network that your office-bound associates a) enjoy or b) suffer. If you operate from a home office on anything more than an occasional basis I think that you should give some serious consideration to maintaining redundant sources of IP connectivity. This is especially true if you rely upon VoIP for your office phones, as we have here for many years.

Redundant IP connectivity can be achieved in a variety of different ways, each with advantages and disadvantages. Performance and price vary widely depending upon the access methods available in your area. For us the best solution has been to use Comcast Business Class cable as our primary internet access, with backup provided by a dry loop DSL circuit from Covad.

It’s important that your two sources of connectivity are different modes of connection, in our case cable & DSL. We could bond a couple of DSL lines and achieve higher speeds, but we’d be susceptible to a single mistake with a backhoe taking out both of our circuits.

I’ve walked down the street, examined the lines and know that the copper goes south down the street while the coax cable goes another direction. No one silly mistake will take them both down.
