weird networking problem resolved
Nearly went berserk this evening trying to surf – some pages would load, others would not. Mac OS X network diagnostics has a row of five ‘lights’ showing the functionality of one’s internet connection – and those marked ’server’ and ‘internet’ were switching from red to green apparently randomly. Web pages would sometimes load – but only after I’d reloaded umpteen times. But my ISP’s home page showed up alright – so I started to think maybe the problem wasn’t local – but ‘out there’. I deleted the first of the four DNS servers I had listed in network preferences (system preferences / network / built-in ethernet) – and bingo: all was well, after an afternoon and evening of frustration.
