It seems like Facebook just went down? Are they getting a DDOS? This would be the first (that I can think of) for the FB Giant...
Update: 5/31/2012 @ 8:34 PM CST
- Facebook seems to be back up. The outage seemed to last <10 minutes. Pretty good to get things back up if it was a DDOS. It seemed to go down about 8:25 PM CST (and I tested it from different Internet Provider - Comcast, Qwest and Sprint). The outage did last (from what we could tell) more than 5 minutes though...
Update: 5/31/2012 @ 8:46 PM CST
- Facebook seems to still be having 'some' response issues. The site is going horribly slow... This typically (when it is site wide on a site as big as FB, on multiple servers, multiple locations, a pretty massive DDOS, though other big sites... like Google, Microsoft, etc are still coming up fast).
Update: 5/31/2012 @ 8:54 PM CST
- Multiple people are talking about FB still "freaking out" on them... making them continually login, connection issues, etc. This is now going on about 30 minutes...
Some thoughts:
Now... more the question is if it was indeed a short DDOS... Why is someone trying to take down Facebook? I know through various news media sources, that the group Anonymous has said that they were going to do it (multiple times, though it seemed to never pan out) and I have always wondered why Anonymous would take down Facebook as it would hurt MANY small businesses... so more my thought is that it is someone attempting to pretend to be the group Anonymous. Interesting thoughts?
If it wasn't a DDOS... is Facebook getting to big?

When Anti-Viruses Go Bad
When Anti-Viruses Go Bad
What happens when your anti-virus turns on you? The simple
answer is your computer stops working.
This was made evident in a recent update to Avira (ironically
only affecting the paid versions of the program and apparently only in 32-bit
environments). After the update, the AntiVirProActiv component began flagging critical
system processes and preventing the computer from booting. In the unlikely case
the system did load, Avira began blocking software programs, virtually all
executable files including Microsoft Office.
The good news is that the free
edition (Avira Anti-Virus Personal) does not include the ProActiv component.
Unfortunately, the paid versions do, including the business edition.
So far, it appears as if affected machines are pretty easily
fixed by updating Avira yet again, a fixed update was released May 15th, but
that was after a supposed fixed update. Avira does give update instructions and a two sentence apology. http://www.avira.com/en/proactiv-application-blocking Also included are instructions to disable ProActiv completely.
While we understand that mistakes happen, there needs to be
better communication from companies in situations like this.
If you use one of the paid versions of Avira, please make
sure that you are not running software version 8.2.10.64. If you are noticing
issues, start a product update. You may need to boot into Windows Safe Mode to
get this to work.
If you need assistance getting this to work, please call us at 612-234-7237. Standard Phone Support is $49.95 per issue. http://stpaulvirusremoval.com/Windows.Repair.Services/PC.Phone.Support.htm

The Ins and Outs of Power Strips, Battery Backups, and Surge Protectors
The Ins and Outs of Power Strips, Battery Backups, and Surge Protectors
by André Thomas
With Spring
storms upon us, strong electrical activity and wind bringing down power lines
become a very real danger for computers. One aspect of nearly all technology is
that it requires a power source; for most of us that means plugging in to an
outlet with power provided by the electric company. Electricity is notoriously
problematic with brown-outs, black-outs, surges, spikes, and plain old
fluctuations. All of these can cause problems for your technology and
especially your computers.
Surges, spikes
and fluctuations can damage sensitive components such as processors, RAM, hard
drives, monitors and video cards. Repeated fluctuations can actually
"fry" your computer. The most instantaneous cause of electrical
damage is a lightning strike which can destroy entire systems in a flash.
Brown-outs and Black-Outs describe actual power interruptions or dips in power
which cause additional wear and tear on the computer, and can additionally
damage data stored on a hard drive and possibly even damage components.
Protection
comes in many forms with varying effectiveness. While none of these are
perfect, they can help protect your investment and your data.
The most
basic, providing no protection, is a power strip. Power strips are of little
use beyond making one outlet into multiple.
Surge Protectors or Suppressors, often incorrectly referred to as power strips, have
a major advantage; they are able to absorb a surge in power. They do however have
a limit to how much they can absorb in a single event, rated in Joules, before
they fail. Many will not survive a lightning strike, sometimes even being
"fried" open allowing the entire strike to reach attached devices. Another thing to be aware of is that this
protection is not immediate, there is a miniscule delay from the beginning of
the surge to when the protection components kick in; this delayed response time
can still lead to problems and still fry your system. An exhaustive explanation
can be found here. http://en.wikipedia.org/wiki/Surge_protector
A Battery Backup or Uninterruptable Power Supply (UPS) is commonly used with critical
systems, and can also be very helpful in a home environment. Their primary
function is to continue providing power in a failure event. While the battery
charge is usually exhausted quickly, it is normally enough time to correct the
failure or shut down the system properly. Battery Backups are most often rated
in VA (volt-ampere) and give an estimated run-time for common equipment uses at
load. Many UPSs will also provide effective power noise reduction and
surge/spike protection and some of the better ones also include power
conditioners. http://en.wikipedia.org/wiki/Uninterruptible_power_supply
Last on the
list, power conditioners. Many high-end
technology devices are susceptible to noise or ‘static’ in a power line. In
these instances, a power conditioner is extremely helpful. They
"clean" or filter your power source and many provide protection from
"cross-talk" or noise from components plugged into the same strip.
The most common application for a home user would be a Home Theater System,
preventing electrical noise from interfering with sound and video quality. Most
conditioners also include a Surge Protectors in the device. Like Surge
Protectors, most have a Joules rating, but also include a decibel (db) rating.
The higher the db rating, the better the noise filtering capability of the
conditioner. http://en.wikipedia.org/wiki/Power_conditioner
One major
note is that all of these devices have an effective lifespan. Most of these are
rated for about 3 years. Surge Protectors can fail much more quickly in areas
with erratic electrical supply and should always be replace after a major event
like a lightning strike. Most Battery Backups can handle a lot more surge
events, but it may wear out the battery faster, and they should be tested
yearly. Power Conditioners are very similar to Surge Protectors, but normally
have longer lifespans. Many products will give estimated life expectancy of the
device in the product info.
