Today, many users have icq, someone earlier, someone later, there was a disconnection from the network and a subsequent error during reconnect “Reservation link error”. The problem affects most popular customers. As a solution, they suggest using alternative addresses of icq servers (some of them help for a short time). Also, some tell how persistence in reconnect has helped them. Some help to wait.
At the time of writing the post, there is no clear information about the causes of the problem and unambiguous solutions. The forums are mostly light panic. The same problem was already in 2006. Passed by herself.
Although most habrayusers, I believe, use more beautiful lamp protocols, and this problem has not affected them much. ')
