Re: Think Broadband Ping Monitor Results (POST YOURS)
Heh. The fact that it's been around for a while but is also intermittent (as in doesn't happen every day) would suggest that it's not an endemic lack of capacity but more likely dynamic changes or failures elsewhere that push more traffic through one particular link than usual. For example the traceroutes above, which show a lots of traffic leaving VM's network normally via different routes but all trying to come back via the 224.22 link.
Who knows. Well, VM's network engineers are supposed to...

maybe cheapskate peering arrangements that buckle on peak times (like new IOS for iPhone like it was 7/8 Nov).

Well, the "recent" issues have all occurred over public peering, and the arrangements there are really "let computers talk to each other and agree routing automatically among themselves using BGP". Each company pays for their own connections to the system, and the system provides automatic connectivity to everyone else at the same speeds. The system doesn't distinguish between providers or destinations and there are no specific arrangement (other than the basic allow/ignore on a provider's ACL)
In this case VM are advertising about a dozen ways into their network (and indeed have around that many physical connections at LINX) - and the public peering exchange on LINX is really just that - a giant public switch where anyone can send data anywhere it pleases. The problem here is too many other providers are sending data back into VM's network through one node and not making sufficient use of the other 8.
Assuming this wasn't caused by a temporary fault elsewhere, this is not a routing or peering issue, it's a load balancing issue. And to be fair, load balancing across two distinct networks, a half dozen locations, a dozen ports, a hundred providers and thousands of routes is a complete bitch to get right.

As before, the blip has a very sharp onset and decline. Something changes abruptly at these times. Here I will allow myself to speculate.
This kind of change is not typical of the gradual build up and decrease of congestion you would expect with folk getting home from work and, later, going to bed. Some change is being made either automatically or manually to network configuration or network load in my area at these times.
Is this local or general? I do not know. How many others are getting this effect and where are they?

Only just started to monitor the BB using think, but I can say my experience is also bad during "contention-rich" periods at night. Last night was shocking up to about 10pm, then I gave up.
I work for a managed provider of cloud services and I know how difficult it can be to have everything running flawlessly all the time. The only difference between the company I work for and VM, is that we actively contact the Customers (or post so they can see) to inform them of what the issue is, and why it's occuring, and follow up with an incident report.
Would be nice if we got something akin to transparency....however coming out and saying "Yeah, we're overloaded" wouldn't help their projections!

Re: Think Broadband Ping Monitor Results (POST YOURS)
Gigantic customer-facing consumer service providers like VM are rarely good at transparency, despite being communications companies (!).
Smaller and specialist providers have it easier providing that "personal touch" but partly that's because anyone who buys a cloud service from yourself will have a level of knowledge much higher than that of the average VM customer. The minimum entry bar is also higher, plenty of VM customers wouldn't have a clue what "hosting" is, the level of information they provide is therefore much different.

Mine didn't have swanky flash animations on it, duh.
Plus, I'm happy being the one that comes up with good ideas and then fobbing it off to someone else to do all the hard work.

Load issues? Slashdot effect? Kinda happens if you get front-paged on a major website because you're so useful.

More cores and an SSD on your webserver, just in case you get popular again.

Re: Think Broadband Ping Monitor Results (POST YOURS)
Got an email off the hosting company this afternoon, ironically the downtime was actually due to them installing an SSD

Re: Think Broadband Ping Monitor Results (POST YOURS)
Oh, it's not a dedicated machine?
And they took it down during the day with no forewarning? Sounds like something VM would do...

Yeah it is, they did tell me though a few weeks ago to be fair, and its an american run company, so things do get done at strange times, despite the server being in the UK
