All SliTaz servers have been more or less uninterruptedly offline since days now. As ping responses are normal and as occasionally bits of a page trickle through, it doesn't look like server maintenance but more like some sort of attack. It would be good if Pascal could post a short message on the mailing list to let the rest of us know what is going on.
One side-effect of all of this is that SliTaz 5 users can't even use the package system in this situation because no matter which other servers (tuxfamily, ibiblio etc.) they have configured, tazpkg always accesses the SliTaz server first and it fails completely if this doesn't respond. One single point of failure ... how stupid! Last night, while all SliTaz servers where dead, I ran SliTaz 3 and installed GIMP from the malibu.tuxfamily server. It was a matter of 3 or 4 seconds and everything worked perfectly. Try doing this in SliTaz 5 now ...
