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.

Problem with Twitter

For more than week I am not able to use the Twitter when I am connected to internet via O2 ADSL here in Prague. I am not alone - friend of mine Mnagas has completely the same problem.
Each time I try to open the Twitter home page in a browser it ends up with the "Connection Interrupted" or "Network Timeout" error.
I spent some time investigating this issue, and found next:
  • it is not a problem of DNS, domain resolves to the correct IP
  • it's not a problem of my machine (friend of mine has same problem, I also verified that from other computers at home I got the same results)
  • I had a chance to test O2 ADSL connection outside of Prague and there it works fine!
  • other Twitter pages like Twitter Status, Twitter Blog work fine
  • BUT pages Twitter Home or Twitter/boruvek always return the error...WTH?!
What shall I do? Am I only a victim of anti-spam / anti-DoS or IP-ban activity from Twitter side? I must say I am bit lost :-) What would you say? Is it a problem of O2? Twitter? :-)




I am quite annoyed. So far I found that only way people to complain about Twitter issues is the GetSatisfaction, which I think is a great support tool and idea, but I do not expect anyone to care about a n issue having single vote only (my question).

As I said I am a bit annoyed about this since I kind of started to like the twitter ;-)

The workaround I found to solve the twitter "withdrawal" is to use the TwitterGadget (Twitter widget for GMail or iGoogle) (via @janecek).

All other desktop twitter client apps (such as twhirl or similar) are facing same connection-problem as described above.
