Hi all,
Jan 24 23:20 - Jan 25 01:45 UK time, from LINX peers I have seen major
performance degradation on unusually strange route to some eastern
Europe countries - see MTR at the bottom of this email.
If this is true, it is exactly what few people told us(and we knew) last
year. Probably AS48400, which is defined as two ISP multihomed
non-transit at RIPEDB, announced various prefixes it had from their
ISP.. actually from one ISP to another becoming a transit ISP. I am sure
this was not the only faulty point in this failure, but it took quite a
while for ISPs to fix it.. It would be interesting to know whether that
was unintentional... I know that at least two countries in that way were
almost taken internationally offline. I wonder if some sort of action
should/will be taken.. Unfortunately ripe's asinuse doesn't tell the
story about 48400, but you would find that in raw update logs and
bgpplay where I counted around 6k AS were affected.
AS PATH 8468 8732 12389 48400 48400 48400 48400 20485 1299 20965 2847
