Q: Safari 9.1.2 suddenly became extremly slow

I am running OSX Maverics 10.9.5 in MBP15 early 2011 i7 2,2 / 8gb / 256 ssd. All lastest updates are installed for this os.

 

Today safari 9.1.2 suddenly became slow as ****. Some pages is loading for about 2 minutes, some are not loading at all (like facebook). It started happening since i turned on my laptop.

I did not install anything right before it happened. I did not change any settings right before it happened. No weird processes are running. Network is fine, but i had troubles connecting to wifi in the begining (my router is linksys ea2600).

 

What i tried:

-restart

-reset safari

-delete history

-disable plugins

-Disable DNS Prefetching in Safari

-manually delete safary cache

-delete safari cache from developer menu

-manually delete safari preferences

-running safari under new, just created user- still slow

-this If Safari doesn't load a page or webpage items are missing - Apple Support

-this If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

-manually enter google public dns into network settings

 

Chrome is working fine, so there is no network problem.

 

I have really no idea what to check else and how to fix it. Please help.

MacBook Pro, OS X Mavericks (10.9)

    Please try to ping ocsp.digicert.com and post results here.


    As a workaround,

    temporary turn off certificate revocation checking - Keychain Access/Preferences/Certificates,

    use Chrome or Firefox,

    or update to 10.10 and up (Apple solution would be to use Sierra :-).

     

    digicert.com knows about this problem (for some reason their servers are inaccessible from some parts of the world; OS X tries to access them when connecting to https sites).

    May I ask - what's your location?

    Are you in Russia? Seems this firewall (?) issue affects only some networks.

    It's a shame, that we haven't checked this before (thinking it's a Digicert/Edgecast misconfiguration),

    but this IP is blocked by Roskomnadzor (https://eais.rkn.gov.ru/) for some unknown reason.

    I think some inappropriate content was published on a site hosted by Edgecast some years ago and Digicert changed IP/DNS last week.

     

    We'll connect both Roskomnadzor & Digicert tomorrow.

    This is not user faul, its's faulty update. Because It's happend on my second Mac mini with clean OS. Before Safari update everything was good and Safari worked very fast.

    Ok, so here is what happened:

     

    29 september 2016 RosKomNadzor has blocked a web site and appliation. It seems that they didnt had any experience and they just blocked ALL tcp/ip connections were created. One of the connections were Digicert center.

     

    Facebook, github and other sites simply stopped working because safari could not check sertificate. Only Russia users were affected.

     

    To use safari again simply add "72.21.91.29 ocsp.digicert.com" without qoutes to your hosts file. Im not sure if this helped or RosKomNadzor unblocked Digicert.
