I can't access Nocster's site or my server. Tracert stops shy of the hostnoc.net router on XO's network. I tried DNSStuff.com's traceroute and it stops same place. Anyone else having problems getting to nocster or having extreme (95%) packet loss?
I was talking to the network admin online right before this started, he's aware of the issue. It looks like a massive flood (incoming on the XO line), which is giving very high latency & packetloss at the PHL router (those are only my thoughts, from what I could see).
Here's a trace that I did save:

Somewhat back up. Getting 700ms pings and about 50% packet loss still.

Just a little rant, but have you ever read their TOS? It says you must open a ticket for packet loss or average access time above 85ms in order to receive credit for a partial month. But Nocster techs complain when you open the tickets. They tell me to wait longer before opening them!?!?!
Average round trip latency for an entire MONTH has to be 85ms or more. Packetloss has to be 1% for a MONTH, or it doesn't qualify. Downtime has to be for more than .5% of the month, or it doesn't qualify. You don't qualify for the SLA this month, which is a good thing
The last set of issues WAS an ATT issue. ATT did verify this over the phone with me, and traceroutes showed the same thing. That took a long time to resolve since Burst doesn't actually use ATT bandwidth, the problem was between ATT & GBLX.
Originally posted by jasonl813 Why does AT&T never show on my traceroutes when it happens? It is always at hostnoc.net that it jumps.
I'm back up too.
You know... There is something called the... "assymetric routing/variance in BGP best path selection"
_Your_ ISP does not think AT&T-->HOSTNOC is the best path, or does not have the path via AT&T to get to HOSTNOC. So _your_ packets get routed via another transit network i.e. XO to get to hostnoc.net.
Hostnoc.net however thinks in order to get back to _YOU_, sending out packet TO AT&T transit is the fastest path.
So when you run traceroute from _your_location_ *to* hostnoc, it goes via non-att network. But when hostnoc runs traceroute *to* you, it goes via at&T, which obviously does not show up in your traceroute b/c that's variance in reverse path (aka, asymetric routing).
This happens a lot on the internet, so nothing to worry about.
The problem is b/c AT&T's peering is all messed up since the last week or two, when hostnoc sends a packet thru at&t, it gets severely delayed on att's network. That's why in your traceroute you see a huge spike of latency as soon as it enters hostnoc.net, b/c hostnoc router was sending packets thru att.
So in other words... in this specific case, it was ATT's fault, none of it is hostnoc's in technical sense.
Originally posted by jasonl813 But then the server traceroute (initiated from the server in cPanel) back to me would show the problem going through AT&T though right? It doesn't and there is still a jump in latency.
If it doesn't show att.net in the path... then it's probably not related to the att issue...
Do you mind pasting that traceroute here? (Feel free to replace octets of the last hop [your home computer] if you want for privacy)
