Poll: most cursed MTU you've encountered in the wild? · Networking

At my day job in Zurich we peer with a tier-1 that announces 9000 internally but polices to 1500 at every edge. The 9000 is "for future use." They've been saying this since 2014. BGP table says one thing, traceroute says another.

Understanding this weird traffic spike pattern · General Discussion

AS-path won't help you here, this is inside your prefix. ASCII art of what you described:

Normal || spike || normal

Flat CPU + 200s + old 404 endpoints = something YOU own is crawling yourself. Check your cron, ch...

Reading between lines of status pages · Reviews

After watching AS64496 and their /22 flap for three hours with zero incident posted, figured I'd catalog the dialect.

[list]
[*]"Scheduled maintenance" = we broke something and need cover
[*]"Degraded performance" = packet loss over 15%, hope you don't notice
[*]"Investigating connectivity issues"...

Poll: How do you handle server noise complaints? · Dedicated Servers

60 days late but did anyone try a closet with a solid core door

I ran a InterServer 2U in a hallway closet for two years, intake through the gap under the door, exhaust into the attic crawl

Measured at 38dB in the bedroom two walls away, no basement needed

The door was the shield, basically

The address space is the real constraint

This is why I asked about ASN. If you bring your own /48 and your own ASN we can do BGP session to the facility edge and both announce cleanly. Without ASN you are begging for static routes or worse, provider NAT. I have seen this...

I wrote a better uptime robot · General Discussion

The graph insight is correct but incomplete. Internet paths are not independent. If you put 3 checkers in ASes that all peer at LINX and LINX has issues, your consensus fails together. Geographic spread matters less than topological spread.

Renewal scam? My annual price doubled but new customers get old rate · VPS Hosting

AS64512 here. My /32 worth of VPS prefixes at Contabo just renewed at €144 instead of €72. Control panel shows $72 for identical new plan. Diagram:

[my account] --renewal--> $144

[new signup] --same spec--> $72

This is standard BGP hijack of your wallet. No RFC cov...

IO wait spikes every Tuesday 02:00 UTC

You have SNMP to Hostinger's hypervisor? No? Then you're guessing from outside. VPS != shared node telemetry. I said get a /24, you said "52 VPS" like that's an achievement. Quantity isn't autonomy.
