RATiO Posted March 6, 2013 Share Posted March 6, 2013 If anyone can solve this I'll be greatful. On my laptop every now and then (maybe 1 in 5) an attempt at loading https://google.co.uk from the favourites bar will fail and I get website not displayed. This happens in both IE and chrome. Happens on home network and at work. Not a major problem just a tad annoying. Anything I can try? Link to comment Share on other sites More sharing options...
+BudMan MVC Posted March 6, 2013 MVC Share Posted March 6, 2013 could be a dns timeout, what are you using for dns? Have you tried it via http vs https - does that have same problem. So do you just refresh and it shows up? if so that could be just a dns timeout problem. So I show that with 300 second TTL, so its not like your machine or even your dns is going to cache that for more than 5 minutes. So yeah if you have slow dns, its quite possible that every now and then when you go to query it, you don't get a response fast enough that your browser says oops. ;; QUESTION SECTION: ;google.co.uk. IN A ;; ANSWER SECTION: google.co.uk. 300 IN A 74.125.225.216 google.co.uk. 300 IN A 74.125.225.215 google.co.uk. 300 IN A 74.125.225.223 ;; Query time: 24 msec ;; SERVER: 216.239.32.10#53(216.239.32.10) ;; WHEN: Wed Mar 6 13:01:55 2013 ;; MSG SIZE rcvd: 78 Also seems like they are doing a round robin sort of thing - so its possible that maybe one of those IPs just does not want to answer, and refresh you hit a different IP. If your really curious - fire up your fav sniffer and see what happens, do you get dns response. Did the dns load from cache? IE you don't see the query, you send the packets and just not get an answer, etc. etc. Link to comment Share on other sites More sharing options...
RATiO Posted March 6, 2013 Author Share Posted March 6, 2013 Doesn't happen on http even though http redirects to https which is weird. Anyway I've just updated the link to http. Happens on http too. I have to refresh for page to load At home my router is providing dns but I have this issue in 2 different locations Link to comment Share on other sites More sharing options...
+BudMan MVC Posted March 6, 2013 MVC Share Posted March 6, 2013 Not really - your router is not providing dns, what your router is doing is forwarding your dns to what you told it to forward too, or just your ISP dns. Now yes it should/could be doing a bit of caching. Or maybe not - I have really never been impressed with dns feature set on any soho router ;) Now I run my own dns forwarder/cache, and quite often do queries directly to the root servers, etc. DNS was just one possible reason you could be having issues, without a bit of investigation you can not rule it out. I would prob as quick easy test, change your machine to use some other dns, be it your isp directly, googledns, opendns, etc. Do you still have the issues? If not then there you go, if so - still does not really rule out dns as not being the problem until you actually sniff and verify that your response time for dns is not the issue, or that your loading the record from cache, etc. it could be a network issue to one of those IPs or all of them since I show them in the same netblock. What IPs are you getting for them? it could be related to delays/errors in browser and the ssl cert. I can load http or https google.co.uk - so you must be running something that is switching you to https. Are you running https everywhere or some other addon like that?
