I have written this issue several times to twitter support account and discussions but twitter has always provided a temporary fix from server side.
Its now become a routine may be I should copy and paste it and save it as word or text document file on my computer so that I may copy paste it every time I face this issue that’s why Facebook is my favorite website to share thoughts and interesting things of my life instead of twitter.
All the profile pictures and images shown on home feed or any webpage showing a twitter image whose source link is on twitter servers as broken or unavailable on all the popular browsers.
I don’t know if its a DNS issue from your server side or from my internet service provider i.e Tata Docomo in #Mumbai #India. But I can assure its not the antivirus software since I also use a mac OS and also tested twitter on my cellphone with a good mobile network provider on 3g plans which has a good network and speed.
Hoping to get a favorable reply and a permanent solution.
