Network Solutions warned on Monday of latency problems for customers using MySQL databases just a week after the hosting company fended off distributed denial-of-service (DDoS) attacks.
"Some hosting customers using MySQL are reporting issues with the speed with which their websites are resolving," the company wrote on Facebook. "Some sites are loading slowly; others are not resolving. We're aware of the issue, and our technology team is working on it now."
Network Solutions, which is owned by Web.com, registers domain names, offers hosting services, sells SSL certificates and provides other website-related administration services.
On July 17, Network Solutions said it came under a DDoS attack that caused many of the websites it hosts to not resolve. The company said later in the day that most of the problems had been fixed, and it apologized two days later.
"Because online security is our top priority, we continue to invest millions of dollars in frontline and mitigation solutions to help us identify and eliminate potential threats," it said.
Some customers, however, reported problems before Network Solutions acknowledged the cyberattacks. One customer, who wrote to IDG News Service before Network Solutions issued the MySQL warning, said he had problems publishing a website on July 16, before the DDoS attacks are believed to have started.
Several other customers who commented on the company's Facebook page reported problems going back to a scheduled maintenance period announced on July 5. The company warned customers they might experience service interruptions between 10 p.m. EST on July 5 and 7 a.m. the next morning.
Donna Marian, an artist who creates macabre dolls, wrote on the company's Facebook page on Monday that her site was down for five days.
"I have been with you 13 years and have not got one word about this issue that has and is still costing my business thousands of dollars," Marian wrote. "Will you be reimbursing me for my losses?"
Company officials could not be immediately reached for comment.
