www.comodo.com down???

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.

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).

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

[kail]

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).

Not a good day.  Has continued to be down frequently when I did periodic checks.

It was down for me too. From 21:45-23:12. I am GMT+1 hours

kail,
  When you gave the wireshark log,what URL were you hitting?
Please do mail me your logs.  All help gratefully received.

Our monitoring shows 100% availability for forums.comodo.com, so either the monitoring system is part of the conspiracy against us (and I'm not ruling it out) or there is some other variable factor here that I'm stilll not getting.

Blas, sded, what URLs were you hitting?  What results /error codes, etc did you get.

Robin

[sded]

I am hitting http and https forums.comodo.com exclusively.  https://forums.comodo.com/comodo_website_issues_for_submitting_website_problems_only-b46.0/ and help for v3, bug reports, unread search.  No real error codes, just hangs and eventually times out usually.  Have you checked your logs for a DOS attack?  The symptoms are similar to others I have seen recently (Broadband Reports had symptoms like this for several days last month and reported it was a DOS attack from the RBN.  Also, Wilders has had occasional problems.)

Hi Robin

The 503s were on CFPs Download page & the forums. I've sent the PCAPs & all the details are in those I believe. Hope it helps.

sded: You probably will not see any errors (see above posts).
