HI

Should be all okay now

Hi

That is because we have activated the port to troubleshoot the issue, you can monitor the task here:

It just seems odd for the two IP's to route differently when it's from the same server to the same destination. It's actually that bad now I can't even browse the site any more or connect to my e-mail most of the time.

Andy BGP is 2 way, it might not be what OVH is done, or not solely what they've done.

Anyway, the whole internet is under attack at the moment/recently, so I wouldn't worry until a couple more days.

HI

I have got 1.4MB Transfer on a 13Mbps line, so no issues here (You can remove it now). LINX have changed some setups and we are checking with them, but it just seems they are trying to manage the attack reported in the media today.

Why would this only affect one of my IP's and not the other? Surely they should take the same route unless it's deliberately set up not to do this by yourselves? I would supply a tracert but I can't because it's a secondary IP.

Can you let me know when you're done with the FTP so I can remove it.

Thanks.

Hi Andy

Just checked and it is most likely related to the attacks at LINX:

LINX Members, Following is an update including the action plan that we've adopted to address the consequences of the recent DDoS attacks against Cloudflare, that affected the Juniper peering LAN, AS5459 and the LINX internal network.

So there might be a few performance issues.

The connection here at work is BT business fibre so it will take a different route.

Hi Andy

No issues here on our BT Connection, is there a file we can test with though just to make sure? I suggest contacting BT, since you may both IPs are okay on your work BT connection.

I'm having routing issues to 91.121.167.122 but my other IP 87.98.249.58 is just fine.

91.* is getting <50KB/s over FTP
87.* is getting my usual 980KB/s over FTP

Seems to be affecting BT routes. OK from work on our BT fibre but my home ADSL is slow as a pig over the 91.* IP but fine on 87.*.

Any ideas please?
