Makes sense, and to be fair i was impressed how quick it was sorted after you raised it

Re: Latency / Packet Loss to Cloudflare

I think "Sir Spiderplant" has a certain ring to it!

Seriously though, I'm very grateful that you hang out here and that you're so proactive in getting things done when us more technical bods think something isn't right.

The funny thing is, that when we spot a fault of this kind (that others probably wouldn't even think is a fault or notice) we are much less likely to even consider talking to customer support because we know beforehand how the conversation is going to go.

The flakyness of the connection is partly what inspired me to write pingnoo, so that I would have the ability to see what was going on with the connection over a period of time, the other part was that pingplotter is crippled and I didn't feel like buying it....so I did what any programmer does, rolls their own.

Re: Latency / Packet Loss to Cloudflare

It's a common failure scenario. One link goes down, other links take the strain and everything looks okay and you can sort the dead link in due course. But because the links and kit on them were specced years ago and are now carrying 25% more traffic individually, they aren't going to handle 2x the present load.

The signs of an overloaded route are also incredibly hard to create alerting for, as different bits of kit will do different things when faced with too much to do. Way too easy to create false alarms and those are the bane of monitoring systems, so unless you know what the failure looks like exactly and it has been accounted for in your alerting, you usually wont know it's happening without someone experiencing it directly.

And don't get me started on asynchronous routing...

Re: Latency / Packet Loss to Cloudflare

Was just working on some stuff and noticed that routing to Cloudflare has changed now, it seems to hop across to Europe for a laugh now.
