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.
