My ADSL line was opened yesterday, so I am back on the Internet! Actually during the last two months, I still had an Internet connection, but only though a 56k modem, not really useable for maintaining Debian packages or for doing an "apt-get upgrade" on my machines (and a bit costly).
I am in my apartment for a month, and it tooks two weeks to get the invoice of my telephone line, one more week to get the ADSL line and one more week to get my modem from the post.
The connection is an ADSL2+ connection, so there is enough upload rate to be able to host websites. I moved all my websites to my home server, and I am just waiting the activation of the reverse DNS to be able to host an SMTP server.
