Our traffic across Telia dipped at 1600hrs UTC yesterday, and recovered 
2hrs later.


No impact, as I'm certain others with resiliency also saw.

Really it depends on the problem source. BGP do not know either route 
really reachable or not. This time we was just lucky.

It was not critical (for us), as traffic was shifted to another links,
and there was no unreachable destinations like BGP announces with
traffic blackholed. But looks strange.


Thats why it is called the bridging gap protocol

While Telia barfed, it bridged the gap.

See, bgp is not all bad. There are no bad routes, only bad days

We have 2 ports from Telia, one in Kiev (Ukraine) and one in New York 
(USA). I have seen both ports simultaneously dropped traffic volume for 
about one hour today.


It was not critical (for us), as traffic was shifted to another links, 
and there was no unreachable destinations like BGP announces with 
traffic blackholed. But looks strange.

Hi everyone,

Looks like the season for outages is on. Does anyone has more details regarding 
the issues at Telia? I didn't found any public available information. They say 
it's over but this is clearly not the case.

Best regards,

Hi everyone,

Looks like the season for outages is on. Does anyone has more details regarding 
the issues at Telia? I didn't found any public available information. They say 
it's over but this is clearly not the case.

Best regards,
Vincentz
