I've been having some connectivity problems off and on the last few | |
weeks due to storms taking out some combination of power/internet or | |
damaging some of the networking equipment here (in spite of the surge | |
protectors, etc in place) as well as a incident with bad wiring | |
getting worse due to storms/electrical shorts. | |
While the iPhone's tethering was a stopgap measure that helped in the | |
meanwhile, it was by no means a final solution, nor did it allow | |
efficient completion of the tasks at hand nor good communication while | |
things were going on as the phone would overheat if I left it running | |
all the time, as the connection is slow. | |
It seemed like sharing what steps were taken to not make this happen | |
again might be useful to some of use in case you want to make your own | |
failover plans and get the required equipment. | |
First off, power upgrades: New battery backups were ordered. This | |
allows considerably more than the 5 minutes of power the current | |
backup does. Additionally, it can power all the networking equipment | |
to follow. | |
Battery backup: http://www.amazon.com/gp/product/B001BTWQDS (works | |
supposedly for 30 minutes, but I've usually found these time periods | |
optimistic). Sticking the networking equipment on this usually allow | |
it to run despite localized power outages. | |
Next off, was a backup to the internet connectivity. The american | |
southeast has been suffering severe weather, tornados, winds, etc for | |
the last month. Atlanta is "The City of Trees" (here is a picture of | |
the area I live in from the satellite: http://goo.gl/FuV3v). It is | |
literally built in a forest. This is beautiful most of the year. | |
However all our power and internet lines are above ground. This | |
combined with trees + wind = relatively easy to knock out utilities. | |
While power is rarely out for more than a few minutes, internet access | |
provided by landline providers goes off for hours occasionally (5-6 | |
times a year). So as a backup for that, I procured a networking plan | |
with Clear.com, a Wimax provider. This runs 52 USD a month with modem | |
lease and unlimited internet. You could ostensibly go down to $32 a | |
month, but there would be limits on the amount of traffic you'd have, | |
as well as your speeds. | |
This wimax router, in the event of a protracted power outage, could be | |
removed from the power at my place of business, and be taken with my | |
laptop to a third place (coffee house, co-working environment, etc), | |
providing unlimited data and a fast connection. Otherwise, it can be | |
used as a near seamless failover when the cable internet goes out. The | |
particular model I have has wifi, so I could also connect up iOS | |
devices to do my work (Which is 3rd Party remote iPhone/iPad | |
development) | |
Lastly, to tie the 2 internet connections together (The old one and | |
the new one), I purchased a dual wan router. This is a product which | |
takes two internet connections and combines them into one (called | |
"Load balancing"), or you can set it up to primarily use one, and use | |
the other in case of failure on the primary, automatically switching | |
over after missing a certain number of pings to a IP or certain number | |
of dns calls to a service, or failures from the gateway. | |
The Cisco RV04 is the dual wan router in question (158 USD): | |
http://www.amazon.com/Cisco-RV042-4-port-100-Router/dp/B0002I7288/ref=sr_1_1?ie=UTF8&qid=1304104670&sr=1-1-spell | |
The setup of this device is not bad. By default it does "load balanced | |
mode" so you do need to customize it to do the failover thing (the | |
manual says how to on page 69),. There is still a 16 second delay in | |
one relatively rare case of no connectivity, but this is still a very | |
good downtime. | |
Upfront cost: $212 | |
Annual cost: $624 | |
So basically very worth it if you work a job which you bill hourly. | |
