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))}
