Update: As noted below, the problems caused by the severed cable are NOT limited to Yahoo! users in India. ALL groups are potentially affected.
That said, it’s certainly possible that other issues, unrelated to the cable, may also be causing some groups to have issues. So if your group is experiencing problems that you believe are unrelated to the cable (and all problems other than delays in messages from the group to individual mail accounts fall in this category), please do what you should always do in these situations: contact Customer Care:
We do read all comment posted on the blog. But the only way to actually get help from Yahoo! with a problem is to contact Customer Care.
The severed cable described in the article above is affecting the data connections for Yahoo! between the US and India. One consequence is that group members may find the delivery of some mail messages delayed until this problem is resolved (which could be days or weeks).
This problem is likely to primarily affect Yahoo! Groups users in India but will not be limited to them. So if you suspect you’re not receiving all messages that have been posted to a group, we highly encourage you to visit the group’s message archive.
