The outages have been periodic for days, not hours. And continue today.
Yes, I know… and I replied. He said hours… and I said no, days! Obviously, he had the wrong problem and/or reason. The problems had already been going on for days by then, the weekend before last they started and, as sded says, they are still continuing today (on & off). Plus see CFPs download page (above), no idea if it’s related or not.
Latest outage was ~1140a to 1240p pdt. Attached is a tracert showing where things dropped out in your neighborhood. This is typical of the outages for the last week, although a bit longer than most.

Went to https, and that helped this time-didn’t on previous attempt. So another tracert

Thanks for that!
I have escalated it.
thanks

I don’t think our firewall is set to allow the ICMP traffic that is required for tracert to trace inside our network.
That’s not to say I don’t think there’s something wrong. There are a few reports of website problems, but I’m having trouble identifying the exact nature of the problem.
There are reports in this thread of problems with forums.comodo.com and download.comodo.com. Do you see problems with any other Comodo sites?
Hi Robin
No, I don’t believe so. The report I made was the first instance that I know of off forums.comodo.com. However, forum members do not spend much time off the forums (edit: as far as Comodo is concerned… didn’t mean they live here).
Note the strange HTTP/HTTPS symptom: When I first tried to answer your post, I followed a HTTP link & it failed (TCP Error, Timed Out)… when I changed HTTP to HTTPS it worked. But, sometimes that logic is reversed & sometimes it doesn’t work period.
I do know what it is that I actually saw on the CFP download page now. The page had not fully loaded. After about a dozen attempts, I saw a fleeting connection to an eu4.something.comodo.com & then the page fully loaded, with the hashes, sizes & download links all present. Something to do with the internal routing possibly?
What the tracert shows is that the path is clear until we get to Comodo. You should be able to trace to the IPs shown from your end if you have a monitoring tool for your network. Also, the second shows it got two hops further than the first toward Comodo for some reason. I don’t think you answer pings either, but was looking for possible network congestion along the way. Nothing. https worked only briefly, BTW.
Note: Ran another tracert with the network working, and the second tracert above does take me to the edge of your firewall, then the expected timeouts.
Kail,
Thanks for the info.
I would have expected you to have been forwarded to eu4.download.comodo.com (or similar) when you actually tried to download the program. download.comodo.com forwards you to a suitable download server to handle the downloads rapidly without taxing our webservers too much.
We’re looking into the problems now.

To be clear. This was before any attempt to download CFP was made. This was just accessing CFPs download page. The sizes & hashes were all blank, and all the download links (for all versions & types) pointed at the same page I was on (maybe an initial state).
(Not sure if its related or relevant) I recently saw a very similar report concerning BOCLean, the user (European) could not get BOC to download & was eventually given a direct US URL by another member. I also tried it & couldn’t initially get it to work either. Here’s what I saw (just happened to copy it)… note the errors…

I’ve been having the same problems listed here on www.comodo.com, http:/https:/ forums.comodo.com as well as download.comodo.com
For me, at least, it’s been alright for the last day or so.
Thanks. We’ve been monitoring overnight. Nothing concrete yet.
We have seen some routing faults between Texas and our DC, but I think kail is UK based so that doesn’t explain his observations.
We will continue to look at the problem today.
I was gettin’ this pretty bad [every other page or so was being dropped] and now I’ve been on for an hour or so without incident. (:CLP) (:CLP) (:CLP)
Yes, I’m in the UK. But, there have been non-European reports. I’ve not noticed any geographical relation as of yet.
However, something else that I previously failed to mention (because it was minor compare to the reported problem)… previously page loads were kinda slow… hanging after displaying the forum header for a few seconds. That’s gone, the pages load instantly today. So, keep your “monitors” running (forever). ;D
Getting problems at the moment… HTTPS is working, HTTP is not (Operation timed out).
Getting more problems here as of 12 AM ish Eastern time in the U.S. https: and http: for forums.comodo.com were both down completely. It gave me a server error of some sort. Unfortunately, I didn’t get a chance to write it down.
It might be worth mentioning that www.comodo.com was up but the forums were also inaccessible from that page.
Im now on https and had no problems today so far, but when it times out it doesn’t matter if the connection is secured or not. Im in central-eastern Europe. For the last 3 weeks I have been experiencing slowdowns too when accessing the forum(Im on an 8mb adsl). When the first connection error occurred I thought the server had reached a bandwidth cap or so. (could it be a DoS??)
Was down for about an hour this morning, 0500-0600PDT, after being pretty solid yesterday. Tried both http and https; no difference. Tracert ended at rembrandt again.
OK, I cannot currently get CFPs download page to load (again). After a dozen attempts, I got annoyed & stuck Wireshark on it. And the answer as to why the CFP download page doesn’t fully load is…
121 14:12:41.156250 85.91.228.132 10.59.180.120 HTTP HTTP/1.1 503 Service Unavailable (text/html)

I have a PCAP sessions of the CFP download page failing to load fully & succeeding (for comparison). I’ll email them to you if you want?
edit: Time reference is GMT +1
Now that I’ve installed PCAP… The Firefox reported “Operation timed out” on HTTP are, in fact, “503 Service Unavailable” as well. The HTTPS failures are slightly different. On many of those the server isn’t responding to the client’s SSLv2 “Client Hello” with an SSLv3 “Server Hello” as it should or the server stops responding during the SSL negotiations, in which there are significant delays. So, for HTTPS, it seems to always be a client issued time-out (so far). This being the case, I suspect the server’s apparent non-responses are probably just longer delays (that are greater than the client’s time-out period).
