O2

Follow-up on Twitter problem

Recently I blogged about a problem I am having with accessing Twitter (see Problem with Twitter) while connected via O2 ADSL here in Prague. I tried to contact Twitter support using email and I also opened a case in the GetSatisfaction system. No feedback (except one guy , O2 customer too, replying that he is having the same issue ).

The problem is obvious – my IP (or better IP range where my IP belongs to) is banned by someone…But who?


Today I contacted O2 support and after three calls I finally ended up on a line with a guy who seemed to be pretty knowledgeable about the possible issues (familiar with IP bans, black lists etc.) and suggested me a workaround. He suggested me to request for a fixed IP address, paid-service provided by O2, and so my IP changes and will be in different IP range than the current.

Now O2 called me again that they found that my IP is indeed on a black lists on „some“ servers, and they are going to investigate why.

Anyway, I am about to try the workaround with the fixed IP address and let’s see if I can open (after several weeks) the Twitter home page 😉

Please unblock the Twitter for me, I am not living in Iran nor in China ! 😉

Another interesting fact is that three out of three O2 people I talked to today (working in O2 Internet ADSL support team), haven’t heard about the Twitter. I do not say it’s wrong or so, but it’s interesting and a bit surprising 😉

Btw. I also found that O2 offers training to corporate customers on how to use social networks like Twitter and Facebook, Webex, and Second life (see one2one) 😉

UPDATE: The workaround with the Fixed IP adress does not help. Original IP address was 83.208.91.xx, the new one (fixed IP) is 83.208.22.xx. Still I am not able to open the Twitter home! Grrrr!
