YouTube is Borked: Pakistani Censors Suspected

It looks like an attempt to censor rightwing arsewit Geert Wilders's anti-Islam home movie has broken YouTube.

Pakistani authorities issued a circular to ISPs in Pakistan demanding that they block access to YouTube; but this doesn't explain why it's unreachable from the UK. A traceroute to goes into PCCW's network and dies; the explanation appears to be that, as mentioned a few minutes ago on NANOG, Pakistan Telecoms has announced a chunk of YouTube's IP address space into the global Internet Routing Table, so traffic bound for them is being misrouted.

This may either be deliberate, or else the result of a BGP leak; whoever it was attempted to reroute traffic to YouTube from their customers to a "site blocked" page and accidentally let the new more-specific route get advertised to the world via their upstream carrier, PCCW. Unsurprisingly, we're not seeing Pakistani splash pages because, well, this suggests that all YouTube's inbound traffic just hit the web server they are using.

(So the comment on my new blog containing a YouTube link will just have to wait for moderation until PakTel either relents, sorts out the important distinction between internal and external BGP, or PCCW filters their BGP announcements.)

The politics are interesting; this comes immediately after a succession of people repressed by Musharraf's emergency rule have returned to the public eye. Talaat Hussain is back on TV, with a pair of banned journalists; their own briefly made a comeback before the cable feed was pulled again. Is Musharraf - or someone - trying to scare them, or seeking an excuse to impose more censorship?

Update: They're back...but they're back from Hong Kong.

Emptywheel thinks this may be some AQ grand strategy:

Your thoughts on the cable cut and cell tower developments?
