If you have a very decent internet connection (equal to or more than 4 mbps) but still not able to stream YouTube video’s without it waiting for buffering a lot, it maybe because your local ISP could be using a CDN for caching YouTube instead of loading from the main site.
There is an easy way to bypass this throttling by asking your OS to block traffic from the caching CDN and loading the content directly from YouTube by simply providing the following command at elevated command prompt
netsh advfirewall firewall add rule name="YouTube Cache Bypass" dir=in action=block remoteip=173.194.55.0/24,206.111.0.0/16 enable=yes
and if you later need to disable the rule use
netsh advfirewall firewall delete rule name="YouTube Cache Bypass"
I am able to feel the difference in YouTube streaming after adding the above rule to the firewall and a happy YouTube customer again 
March 31st is world backup day! Signup for a cloud based backup service and save yourself a lot of regret later.
I am singing up for Backblaze since they are providing an option for unlimited space and unlimited individual file size for $5/month (AED 19/month), which is a small amount to preserve all my important stuff.
You can also check out Crashplan who have some really attractive annual and biannual plan.
