In th second week of September, 2012, PTA has blocked access to youtube.com in Pakistan by asking ISPs to block access to the website. It is not clear what procedure is adopted by the ISPs to block Youtube. I think all the ISPs in Pakistan have used their own policy and mechanism to block these services. This has resulted in different kind of blocked reports from different users. e.g many users were reporting that they were able to access the youtube through secure http protocol ( https ). At this time on 23rd September, youtube is not accessible through https on PTCL and others network. ( I can confirm
The widely used Gmail services have not seen any services interruption yet. However, Google Maps, Google Drive and google plus have been inaccessible most of the times.
This is yet to ascertain how much loss has happened to Google and local business that are using Google services. May be we have some data in near future on this.
As a website visitor when someone goes to the website the browser keep its status transferring until all the page content is loaded. As the Google analytics file is not loading on user's computer the browser keep showing the in-progress status. This means the page load time increases to more than 2 minutes in most of the cases. In addition to long page load times some of the java scripts does not get executed that are required for various interactions on the website.
I have studied various files in BrightSpyre.com that are being loaded from Google servers. We have commented out Google analytics code and now the page load time has come back to normal. Also in some pages jquery code was not executing and that pages have started working smoothly.
We still running Google adsense and Google ads managment software on BrightSpyre.com. However, both of these services use a different web address ( googleadservices.com and googlesyndication.com, googleapis.com) and run smoothly without any page blocking.
