According to NDTV 24X7, an Indian news channel, the clampdown on blogsites (and some websites) is NOT connected to the recent blasts in Mumbai, but is an effort to curb the propagation of religious extremism on the Net. If that's true, the ban may not be lifted any time soon.
If it's not clear from what has been said so far, the Indian ban applies to ALL blogs from these sites, not just those originating in India: ALL blogspot, typepad, geocities blogs worldwide. If you have a blog from one of these providers anywhere in the world, I cannot read you.
It's odd that we can still post to our own blogs, and read the blogs that we have had the foresight to subscribe to through RSS. These loopholes may well be closed soon, if this is to be a long-term policy.
Meanwhile, there's a workaround which allows me to read Blogspot blogs, but it's getting a lot of publicity, so it may not last long. It doesn't seem to work for Typepad. Movable Type is not affected -- no religious extremists there, apparently.
