Fight Internet Outages with Logic -- Not By Switching Providers

att-uverse_2.jpgTake a real world scenario we just recently helped a client solve. A mid-size firm that is using a Comcast Coax connection of (100 Mbps down, 25 Mbps up) was having problems with an occasional outages some lasting an entire work day. This would happen a few times a year.

Out of pure frustration, they wanted to change providers, and we put into motion an alternate plan that would save them countless dollars over the long run.

We recommended to keep Comcast and add a AT&T Uverse / DSL backup line along with the latest firewall from Meraki (MX64W), which can support about 50-75 active users, 200Mbps of firewall throughput, and full gigabit integrated switch with dual gigabit WAN connections.

The Meraki firewall also has built-in WiFi capabilities, which include dual-band concurrent 802.11G/N/AC at both 2.4 and 5GHz. For a unit cost under $800USD (unlicensed), this is an absolute bargain for an AC-enabled WiFi firewall.


Now, we have our two internet lines configured in link aggregation mode, which is Meraki's codeword for what many call "load balancing" and active failover. We selected a primary uplink line (Comcast, in our case) and yet still choose to have both lines working in a load balanced manner, with traffic flowing between both pipes depending on bandwidth rates that are manually specified for what each pipe can handle.

In the event where our Comcast line goes out, for example, the AT&T Uverse / DSL line takes over in short order, with all traffic being passed over that pipe until Comcast comes back up. And of course, vice versa. And for those with larger offices, they can take advantage of content caching from Meraki MX80 series, which can help reduce strain on smaller WAN pipes that have unusually large user counts.

The proof of concept was realized not too long after our implementation was completed. With Meraki’s consistent monitoring and alerts we witnessed the Comcast line go off-line and the traffic switched within 90 secs. Most users did not even notice the internet briefly went down!

On that day, the internet was down all day (8 hours). The owner did not have to send employees home or pay them to not work. Their office had approximately 80 users and with an average hourly salary of $25 an hour. With the possibility of burning $2000 an hour of just salaries, not even considering loss of potential clients or additional revenue. This solution is a no-brainer!
