Server Problems iPhone

Often now my iPhone can't open any pages because the server doesn't answer - but on the iPad everything is fine. Anybody know, why just not on the phone?

may be the network is slow on that phone

if it sometimes connect and sometimes fails to connect then it may be a network problem

Are the problems related only to a certain site?
