Hey, don't blame the government for everything. People used to blame the government even if they can't swim.
Do not forget that without this government, we would have still travelling in roads with utter fear of life.
Anyway, It must be your ISP who blocked it. They may be given orders by a higher authority with proven facts on the bad side of youtube. Or else it can be auto firewall rule placement due to virus attack. You need to wait and see. If you are in a real hurry, then call your ISP and ask why it is not working.
Since you said da... government, something came to my mind
Some people train youngsters to blame the government if they do not get a job after completing their ART degree. Those guys are getting educated from the government using public funds and after education they start demanding the government to give them jobs. Who asked them to do ARTS? In every school ART is done by the most week students who couldn't do maths, bio or commerce (I'm talking about the truth here). It is very rare to see a real talented student even in ARTS who selects ARTS stream. This country doesn't need 1000s of ART graduates. This is a waste of public money to educate them. This country needs more engineering graduates. Even I haven't seen engineers who are blaming the government demanding jobs. Since those ARTS students are children of this country, now it is the time to give them fully fledged technical education. If they have 9 subjects, 8 should be technical like mathematics, physics, computer programming, graphic designing, etc.... 1 can be Sinhala literature, religion, history, etc.... The people who got the best results in ARTS need to be given provision to select all ART subjects.
Though it is a bit out of topic, I thought I would tell you how unreasonable to blame "government" (whether it is UPFA or UNP) for everything. If it is raining -> blame government, if it is not raining -> blame government

. As young generation, I think you should not continue this joke.
Just give a call to your ISP and see what you get.
With SLT ADSL, it works fine.
