- The more switches a packet has to go through, the higher the latency, so your response times may deteriorate if you cascade too many switches. Legend says up to 4 is a good number, any further you risk creating a big mess. - The more switches you add, the higher your bandwidth utilized by

Re: Question about co-lo in APAC region

Personal opinion: developing countries tend to have unstable utility service (power is what matters here), so your DC of choice in India should be Tier 4 preferably, which are hard to find and really expensive. Budget allowing, I'd stick to Hong Kong, Shangai or Singapore as you mentioned

Re: ADSL Line Extenders

Semi-related question: in instances like this, wouldn't a point-to-point link provide larger throughput and be less expensive? Unless you are talking about several subscribers that are already installed and operating. Depending on the situation, it might make sense to set a few sectorial antennas

Re: rack cable length

Hi Shawn, If you don't leave slack, you can't really pull the server out of the RU for maintenance (hot swaps, etc). Your best choice is to purchase cable management trays if that makes sense (Dell servers usually come with those). Otherwise you just need to deal with the loops and whatnot the

Spam coming from (possibly) GoDaddy servers - anyone on the list?

Received some fake FedEx emails coming from secureserver.net servers that afaik belong to GoDaddy. I can give more details if someone speaks up. GMail anti-spam only picked up a few of these, others went straight through to inbox. Regards, Rafael

I am a huge fan of FreeBSD, but for a medium/large business I'd definitely use a fairly well tested security appliance like Cisco's ASA. Depending on the traffic you have on your fiber uplink, you can get a redundant pair of ASAs running for less than $2,000 in the US. I just find it less

Re: Comcast Static IP Changed With New Modem?

I've had a similar mistake happen with TWC. It's most likely a glitch in their config system which should use the gateway's mac address in order to assign a static IP on the docsis modem. Tech support should figure this out pretty quick without escalating it much further. I've had an instance

Re: abuse reporting tools

Some folks might disagree with this, but if it's an important service that I have running on a network, I will block a series of garbage AS's (closer to /8 the better) at the firewall (not at the edge) and that reduces the headaches by 50%. This isn't practical at the edge, but for system
