Google has blocked access to Twitpic.com, a popular photo sharing tool for Twitter, after identifying it as a malware risk. Some users are also complaining that Twitter’s own t.co URL shortener service is also broken at the moment but we are not sure if the two are incidents are linked in any manner.
Interestingly, pics posted via Twitpic appear in the expanded mode on Twitter when viewed on Google Chrome. We should hopefully get an update soon on the situation. It is unlikely for the block to remain for long and in all probability the affected services are working it with Google as we file this post.
UPDATE: Twitpic denies there is anything wrong with its service to invoke the malware notice and is trying to contact Google.
