As you are probably aware, Ubuntu uses CC.archive.ubuntu.com with "CC" being a two-letter country code. Any country that doesn't have its own mirror is referred to the very same "main" servers. Since both Canada and the USA do not have repository mirrors, they too automatically use the main servers. These are located in the United Kingdom, and may be slow depending on load (gutsy beta was just released when this bug was filed) and distance to your location. Current download speed seems fine at well over 50 mbit/s.
Note that as a result of the above, there will be no difference between using the ca or us archive at this time. All but one of the forum threads you listed are ancient history and thus may not reflect the current situation. For fast repositories, your best choice is probably a western-European mirror like nl, ch, se, dk, be. ** Changed in: ubuntu Status: New => Invalid -- Canada Ubuntu repositories are unstable and slow https://bugs.launchpad.net/bugs/148233 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
