IS Routing problem

[timhaak]

Hi

Does anyone else have a problem with IS routing. Trying to get to a work server thats on a IS uncapped account at work from a IS capped account. Have not reached cap but that should not be a problem either as its local to local. Also have tested to see if I can get to the server from a US server and can.

This has been going on since last week (possibly longer as only became aware of it then)

Anyone have any ideas?

Trying to get to 196.213.94.50 from 196.209.18.83

Thanks . Should from what I understand be IS to IS so weird that there own internal routing is broken.

 

[Numchuck]

Nothing weird about that... their network is full of "tweaked" routing that has started causing problems all over the place, plus the fact that they are horribly over subscribed. Nothing beats SAIX at the moment I'm afraid

Ah well looks like I will be moving to a SAIX account as of next month. Pitty have a 12 month contract at work with IS.
