Our DNS servers are currently being used in a DNS amplification attack. Our NOC is currently doing its best to block off as much as possible.
You may have issues reaching some websites during this attack. It’s best to retry again when a lookup fails.
We apologize for the inconvenience.
In order to execute the final step in improving our mail servers, we have planned a scheduled maintenance on the 16th of March, at 01:00 CET.
Affected services: E-Mail
Maintenance window: 01:00 – 02:00 CET
Downtime: 1 hour
During the maintenance our mail servers will not be reachable. Your emails will not be lost.
We apologize for any inconvenience.
Betreft: E-mails
Onderhoudstijdstip: 01:00 – 02:00
Duurtijd: 1 uur
Gedurende dit onderhoud zullen onze mailservers niet bereikbaar zijn. Uw e-mails zullen niet verloren gaan.
Wij excuseren ons voor het ongemak.
A fiber cut in London and a planned maintenace in Rotterdam cause internet connectivity issues. We try to resolve these as soon as possible. Sorry for the inconvenience.
Dear customers,
Since 2:30 we are having a problem with Voip and SIP trunks, including our own telephone systems. We are currently not or difficult to reach via telephone.
Our network team is currently trying to resolve this issue as soon as possible.
More news will follow.
Update 18/02/2014 – 10h15
Update 17/02/2014 – 16h47
12 individual spamhaus listings are blocked. 8 are acknowledged by Spamhaus. We are waiting for the last 4 listings remaining. After we surely hope Spamhaus can deblock our entire IP range.
Dear customer,
Spamhaus.org listed our IP ranges, due to 2 customers who seems to be spammers. Meanwhile our NOC team took the necessary steps to block these spammers, but you are unable to send mails to people who use spamhaus.org as a filter to receive e-mail.
As we already communicated in the past, spamhaus.org always take extreme measurments by blocking entire IP ranges, instead of the one specific spamming IP address.
As an ISP we do not do any filtering of traffic and we do allow fixed IP users to have their own mail servers, but we try to pro-actively scan as much traffic as we can for possible abuse. We already redefined our policy regarding traffic filtering to prevent such issues, but it seems now that we need to protect ourselves and our customers even more.
We still believe that over the years we already took quite a lot of measurements to get the internet free from abuse and spam as we closed port 25 for all our dynamic IP users and we implemented a state of the art Cisco Iron Port mail system.
Nevertheless we still do not do any traffic filtering and we don’t want to.
We are in contact with Spamhaus.org in order to delist our IP-ranges as soon as possible.
Our network engineers will replace the battery backup units on our data storage servers.
During the maintenance our mail servers will not be reachable. No email will be lost.
We apologize for any inconvenience
Update 1 – 17/02/2014 09:00
The maintenance has been completed. The mailserver is operational again.
If this is the case, we can advise you to use a different DNS server, for example Google’s public DNS.
The IP addresses of these servers are 8.8.8.8 and 8.8.4.4. For instructions on configuring these servers, you can head to this website.
We apologize for any inconvenience.
Update 2 – 13/02/2014 11:45
We have resolved the situation, both DNS servers are working properly again.
Update 1 – 12/02/2014 11:45
We currently have a temporary solution in place. The working DNS server is now set as primary. A quick restart of your modem should apply the changed settings.
The cause of the failure is under investigation in dialogue with our supplier.
All services were restored automatically. If you have no Internet after the outage we advise you to restart your modem first.
We apologize for the inconvenience.
Update 13 – 21/01 17:03
We schedule a maintenance, tomorrow morning at 05:00, to improve the performance and stability of our mail servers. During the maintenance all mail service will be temporary unavailable. No mail will be lost.
Maintenance will start on 22/01 around 05:00 and will take about 30 minutes.
Update 12 – 20/01 10:30
After the works of this weekend it seems that we have found the origin of the slow responsiveness of the mail servers. By replacing the defect disk controller in our main storage server the speed of our mail servers increased drastically. Monday morning we had our first real stress test by you as customer (Monday morning is the most busy time frame in the week for our mail servers) and the response time of our mail service stayed normal. We keep on monitoring our mail system but we presume this issue finally is solved.
Update 11 – 18/01 10:29
Yesterday evening we found another problem with the storage systems, we completely replaced one of the storage systems, this device is now replicating data, and should be finished today. We also needed to replace a defective disk controller in another storage system, this night this controller started working as it should again. Due to the fact that the load is lower in the weekend and at night, everything should anyway work optimal. We need to wait until Monday to see if the problem rises again. We are very sorry for the lack of communication yesterday, we were working very hard, but had no updates.
Update 10 – 17/01 10:57
Update 9 – 16/01 16:40
Together with our software supplier we are currently implementing a new possible solution. During the next hours and night we will monitor this new implementation to see if it gives the necessary speed gain. We keep you up to date as soon as we have more feedback.
Update 8 – 16/01 10:52
Meanwhile our technical team contacted our hardware supplier in order to find the possible cause and solution. We keep you up to date as soon as we have more feedback.
Update 7 – 15/01 20:15
Our technical team had to bring webmail off line in order to continue to search for a solution for our e-mail delays. We keep you up to date as soon as we have more feedback.
Update 6 – 15/01 17:04
Our technical team is working non-stop to solve the mail issue. There are several problems causing e-mail to slow down. Our technicians are excluding several possible issues one by one. Every time we get one step closer to a solution. As soon as we have more feedback we will keep you informed.
Update 5 – 15/01 11:03
The scheduled maintenance of this night did not completely resolve the issues, therefore we need to schedule another maintenance as soon as possible. Our mail systems will go completely offline at 12:00 for 20 to 25 minutes.
Update 4 – 14/01 14:39
The data has been rebuilt but our systems are still causing time-outs. Our network team will perform a maintenance tonight (Starting at 01:00) to resolve the issues. During this maintenance you will not be able to receive any e-mails. We expect to resume full service by tomorrow morning.
We can confirm that no data is or will be lost.
Update 3 – 13/01 13:13
We expect that the delay for receiving email messages will be solved within 48 Hrs. The delay is caused also due to the high load during working hours. Edpnet is doing everything to speed up ongoing processes
Update 2 – 09/01 10:30
Our data storage system experienced a big failure. No data is lost and everything kept on running. The system is currently rebuilding a lot of data and responds slow. You can experience time-out when retrieving your e-mail. Please try again after a few minutes if you have a time-out. Completely resolving this issue will take some days.
Update 1 – 14:43
The issues were temporary resolved but have returned, our network team is still looking in these issues. We thank you for your patience.
Due to a failure on our e-mail system we have to perform an unforeseen maintenance right now. You won’t lose any mails. Please be patient if your e-mail isn’t working at the moment.
Thank you for your understanding.
Edpnet apologizes for any inconveniences.
