Of course, if you have activated internet access and automatic updates 
in the preferences tab/Access to Internet/Wolfram Alpha.

Test:

It is working even on sundays (23.6, 4.00 UTC)
and now we get a reasonable result in an acceptable time.

In[21]:=
Timing[ Integrate[
   Sin[x/2]^2/x^2/(x^2 - 4 \[Pi]^2)/(x^2 +
      b^2)^2, {x, -\[Infinity], \[Infinity]}, Assumptions -> b > 0]]

Out[21]= {32.074, -((
   b^5 + 2 b^2 (-5 + 4 b) \[Pi]^2 + 8 (-3 + 2 b) \[Pi]^4 +
    2 E^-b \[Pi]^2 (b^2 (5 + b) + 4 (3 + b) \[Pi]^2))/(
   8 b^5 \[Pi] (b^2 + 4 \[Pi]^2)^2))}
