Should there be an internet blackout (for whatever reasons), here are some ways to reconnect.
From Liberty News Online:
Scenario: Your government is displeased with the communication going on in your location and pulls the plug on your internet access, most likely by telling the major ISPs to turn off service.
This is what happened in Egypt Jan. 25 prompted by citizen protests, with sources estimating that the Egyptian government cut off approximately 88 percent of the country's internet access. What do you do without internet? Step 1: Stop crying in the corner. Then start taking steps to reconnect with your network. Here’s a list of things you can do to keep the communication flowing.
PREVENTIVE MEASURES:
MAKE YOUR NETWORK TANGIBLE
Print out your contact list, so your phone numbers aren’t stuck in the cloud. Some mail services like Gmail allow you to export your online contact list in formats that are more conducive to paper, such as CSV or Vcard, and offer step-by-step guides on how to do this.
BROADCAST ON THE RADIO:
CB Radio: Short for "Citizens Band" radio, these two-way radios allow communication over short distances on 40 channels. You can pick one up for about $20 to $50 at Radio Shack, and no license is required to operate it.
Ham radio: To converse over these radios, also known as "amateur radios," you have to obtain an operator's license from the FCC. Luckily, other Wired How-To contributors have already explained exactly what you need to do to get one and use it like a pro. However, if the President declares a State of Emergency, use of the radio could be extremely restricted or prohibited.
GMRS: The General Mobile Radio Service (GMRS) is a licensed land-mobile FM UHF radio service in the United States available for short-distance two-way communication. It is intended for use by an adult individual who possesses a valid GMRS license, as well as his or her immediate family members... They are more expensive than the walkie talkies typically found in discount electronics stores, but are higher quality.
Family Radio Service: The Family Radio Service (FRS) is an improved walkie talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies in the ultra high frequency (UHF) band. It does not suffer the interference effects found on citizens' band (CB) at 27 MHz, or the 49 MHz band also used by cordless phones, toys, and baby monitors.
Microbroadcasting: Microbroadcasting is the process of broadcasting a message to a relatively small audience. This is not to be confused with low-power broadcasting. In radio terms, it is the use of low-power transmitters to broadcast a radio signal over the space of a neighborhood or small town. Similarly to pirate radio, microbroadcasters generally operate without a license from the local regulation body, but sacrifice range in favor of using legal power limits.
Packet Radio Back to the '90s: There do exist shortwave packet-radio modems. These are also excruciatingly slow, but may get your e-mail out. Like ham radio above it requires a ham radio license because they operate on ham radio frequencies.
TELEPHONE:
Set up a phone tree: According to the American Association of University Women, a phone tree is "a prearranged, pyramid-shaped system for activating a group of people by telephone" that can "spread a brief message quickly and efficiently to a large number of people." Dig out that contact list you printed out to spread the message down your pyramid of contacts.
Enable Twitter via SMS: Though the thought of unleashing the Twitter fire hose in your text message inbox may seem horrifying, it would be better than not being able to connect to the outside world at all. The Twitter website has full instructions on how to redirect tweets to your phone.
Call to Tweet: A small team of engineers from Twitter, Google and SayNow, a company Google acquired recently, made this idea a reality. It’s already live and anyone can tweet by simply leaving a voicemail on one of these international phone numbers (+16504194196 or +390662207294 or +97316199855) and the service will instantly tweet the message using the hashtag #egypt. No Internet connection is required. People can listen to the messages by dialing the same phone numbers or going to the Twitter account, speak2tweet.
Alex Jones and infowars.com have a telephone number for people to listen to his radio show by phone, in case the internet goes down, or if you don't have internet. The phone in listen line is 512-646-5000.
FAX:
If you need to quickly send and receive documents with lengthy or complex instructions, phone conversations may result in misunderstandings, and delivering the doc by foot would take forever. Brush the dust off that bulky old machine, establish a connection by phone first with the recipient to make sure his machine is hooked up, then fax away.
You may not need a fax machine to send or receive faxes if your computer has a dial-up fax application.
NON-VIRTUAL BULLETIN BOARD
Sometimes we get so wrapped up in the virtual world that we forget about resources available in the real world. Physical bulletin boards have been used for centuries to disseminate information and don't require electricity to function. If you are fortunate enough to be getting information from some other source why not share it with your friends and neighbors with your own bulletin board? Cork, magnetic and marker bulletin boards are as close as your nearest dime store and can be mounted just about anywhere. And if push comes to shove you can easily make your own with scrap wood lying around the house.
Getting back online While it might be relatively easy for a government to cut connections by leveraging the major ISPs, there are some places they wouldn't get to so readily, like privately-owned networks and independent ISPs.
