How Much Does Your Work Depend on the Internet?
malord asks: "I work for a small company that has recently had problems finding a stable internet connection. It started when we moved our office in order to upgrade our connection speed. We decided to go with cable internet through Comcast, since they offered the best speed for the price and told us that it would be available before we moved. Unfortunately, Comcast did not provide any service for two months after we moved, so we piggy backed on an existing (slow and unreliable) wireless account with another company in the meantime. When Comcast finally came around, the service that was provided was far from adequate with a consistent 30% packet loss and multiple disconnects everyday, which was confirmed through Comcast's tech support. Throughout this process, we have realized that having a reliable internet connection is more important than having a phone line and almost as necessary as electricity. What would you do if your internet was suddenly like dial-up for weeks at a time? How much money would your workplace lose if it was out for an hour or an entire day?"
> We decided to go with cable internet
Mistake #1.
You're a business. There's no reason a business should be using anything less than SDSL. It costs more for a reason - it's reliable.

That means they guarantee it'll be fast, it'll work, and if it doesn't, they'll fix it fast.
If a couple hundred per month for internet is too much for your internet-dependent business it sounds like you've got bigger issues than packet loss.
And THAT'S why redundant feeds from different providers is necessary for any peace of mind. By the time I left my last job I had two T-1's from different providers entirely (I checked to make sure the cables were physically different coming at us via different paths), plus a third fiber optic feed. I was close to adding cable as a fourth. If the Net went out at that place I would have literally hundreds of people pissed within ten seconds. So have redundant feeds, redundant routers, redundant servers, redundant backups. Did I mention that redundancy is important?
How about a moderation of -1 pedantic.
I can't recommend them highly enough. Pick-up-after-a-few-rings, by-a-person-who-can-talk-dBs-and-DNS grade service, 24/7.
And that's on their residential product.
Um... It's pretty much been standard practice since day one. It's how the Internet provides robust routing. All businesses relying on their network should be doing it. Diverse home networks? Depends how important your porn supply is to you.

we're right on the border to where Medicom and Comcast seperate.. and verizon is simply a joke.. I've actually contacted the President of Verizon for Delaware's district, to no avail.. One of those typical, "I'll get back to you on that" phone calls.. For us to get DSL, would require them to spend a few thousand dollars in running new lines underground, as well as special hardware for the fucking FIBER FED PG BOX literally a hundred yards from our office.. Cable companies have also said, that they'll need to dig underground, costing thousands, just to lay some cable to our little warehouse..
I've thought of every possible solution, and they are either too cost worthy, or they simply won't work.. we can't afford to have downtime, and dialup is better than nothing at all.. but I did do the math, and we lose a maximum of a 1000 hours every year in productivity due to waiting for pages to load, uploading high res images for products, and the bulk submission of hundreds of ebay items.. ahh well.. i've definitely gotten used to it, but it makes me wonder how much more money we could make, if we just had a faster internet connection.. I certainly understand that even a crappy satellite investment could help us out big time.. but my bosses are still struggling to pay the monthly bills, so its really out of the question until someone like Verizon, Mediacom, or Comcast can offer a decent $30-70 a month internet connection..

We are in the similar situation having Exchange in-house behind a (quite stable) DSL line. Thankfully the DSL has been out only about 30 minutes total in our first year, but unfortunately our Exchange server can't say the same. We've gotten an amazing value using a backup mx service, which silently queues mail for us until our server returns. It works amazingly well-- once our server is back up, the queued mail comes flowing in. Its a beautiful thing.
We specifically use EasyDNS's DNS service which includes the backup MX service. We use their DNS Plus service which only costs about $40/year, and allows us to use their CLUSTER of backup MX servers (How cool is that!?)! Its also available on their DNS-only service (~$20/yr). I don't work for EasyDNS (just a happy customer). You can also get the same service from lots of other places as well.
Realistically, I think you need to use an external DNS service to do this for network outages (since other mail servers will need access to your domain's MX records to find to the backup MX servers). For us, this meant we needed to use a different DNS server inside our local network. The external dns points people to our mail server's public IP. The internal dns points to our internal ips.
Another note, we use PFSense as our firewall (great product!). Recently, I think I saw support for NAT Reflection was added (allowing internal machines to contact internal servers using a public IP address), which might negate the need for the "split" dns described above. Haven't tried that yet, though.
Not if he hosts DNS behind the T1. All SMTP servers I know of cause permanent failure when they can't look up the MX record. This is why you should always have redundant DNS. I can see letting a backup MX slide as it can be complicated to set up, but hosting all DNS behind one connection just shows you don't care.
I suggest you get your own local test environment (IIS box, Apache box, etc) - regardless of the internet connection being up or down, you'll get far more work/testing done if it's hosted locally.
I run: Windows, OS X, Linux, FreeBSD. Just because you have a hammer, doesn't mean everything is a nail.
malord may need a Motorola 484095-001-00 Signal Booster. Check your cable modem's internal webserver at http://192.168.100.1/ and if you do have a weak signal problem like I suspect (see Comcast's support forum and/or the Comcast forum on dslreports.com for how to do the diagnosis) then buy the amp. Yes, you shouldn't have to, but it's your best chance to actually fix the problem. Install the amp at the earliest possible point, before any cable splitters (if you have any).
If Comcast had any brains they'd keep a whole bunch of these in every Comcast service guy's truck and train their people to read the cable modem's signal status page. It'd be a helluva lot cheaper than repeated truck rolls to the same very annoyed customer. Better yet, they'd replace more of their aging copper with fiber before FiOS poaches all their best customers (alas, I'm in SBC/AT&T territory), but that's another rant entirely. Overall I'm reasonably happy with Comcast in my area but I'm still jealous of folks who can get FiOS.
